a fix in the bootloader which will apply a fix for those headings, but old apps may
still expect an inverted value.

`hdop` is a value from the GPS receiver that gives a rough idea of accuracy of
lat/lon based on the geometry of the satellites in range. Multiply by 5 to get a
value in meters. This is just a ballpark estimation and should not be considered
remotely accurate.

do:
```

immediately. Terminal and vertical scrolling work (horizontal scrolling
doesn't).
* `Bangle.setLCDMode("doublebuffered")` - The drawable area is 240x160 16 bit,
terminal and scrolling will not work. `g.flip()` must be called for draw
operations to take effect.
* `Bangle.setLCDMode("120x120")` - The drawable area is 120x120 8 bit,
`g.getPixel`, terminal, and full scrolling work. Uses an offscreen buffer
stored on Bangle.js, `g.flip()` must be called for draw operations to take
effect.

Overlay an image or graphics instance on top of the contents of the graphics buffer.
This only works on Bangle.js 2 because Bangle.js 1 doesn't have an offscreen buffer accessible from the CPU.
```
// display an alarm clock icon on the screen
var img = require("heatshrink").decompress(atob(`lss4UBvvv///ovBlMyqoADv/VAwlV//1qtfAQX/BINXDoPVq/9DAP

Bangle.setLCDOverlay(img,66,66);
```
Or use a `Graphics` instance:
```
var ovr = Graphics.createArrayBuffer(100,100,1,{msb:true}); // 1bpp
ovr.drawLine(0,0,100,100);
ovr.drawRect(0,0,99,99);
Bangle.setLCDOverlay(ovr,38,38);
```
Although `Graphics` can be specified directly, it can often make more sense to
create an Image from the `Graphics` instance, as this gives you access
to color palettes and transparent colors. For instance this will draw a colored
overlay with rounded corners:
```
var ovr = Graphics.createArrayBuffer(100,100,2,{msb:true});
ovr.setColor(1).fillRect({x:0,y:0,w:99,h:99,r:8});
ovr.setColor(3).fillRect({x:2,y:2,w:95,h:95,r:7});
ovr.setColor(2).setFont("Vector:30").setFontAlign(0,0).drawString("Hi",50,50);
Bangle.setLCDOverlay({
width:ovr.getWidth(), height:ovr.getHeight(),
bpp:2, transparent:0,
palette:new Uint16Array([0,0,g.toColor("#F00"),g.toColor("#FFF")]),

Set internal options used for gestures, etc...
* `wakeOnBTN1` should the LCD turn on when BTN1 is pressed? default = `true`
* `wakeOnBTN2` (Bangle.js 1) should the LCD turn on when BTN2 is pressed?
default = `true`
* `wakeOnBTN3` (Bangle.js 1) should the LCD turn on when BTN3 is pressed?
default = `true`
* `wakeOnFaceUp` should the LCD turn on when the watch is turned face up?
default = `false`
* `wakeOnTouch` should the LCD turn on when the touchscreen is pressed? default
= `false`
* `wakeOnTwist` should the LCD turn on when the watch is twisted? default =
`true`
* `twistThreshold` How much acceleration to register a twist of the watch strap?
Can be negative for opposite direction. default = `800`
* `twistMaxY` Maximum acceleration in Y to trigger a twist (low Y means watch is
facing the right way up). default = `-800`
* `twistTimeout` How little time (in ms) must a twist take from low->high
acceleration? default = `1000`
* `gestureStartThresh` how big a difference before we consider a gesture
started? default = `sqr(800)`
* `gestureEndThresh` how small a difference before we consider a gesture ended?
default = `sqr(2000)`
* `gestureInactiveCount` how many samples do we keep after a gesture has ended?
default = `4`
* `gestureMinLength` how many samples must a gesture have before we notify about
it? default = `10`
* `powerSave` after a minute of not being moved, Bangle.js will change the
accelerometer poll interval down to 800ms (10x accelerometer samples). On
movement it'll be raised to the default 80ms. If `Bangle.setPollInterval` is
used this is disabled, and for it to work the poll interval must be either
80ms or 800ms. default = `true`. Setting `powerSave:false` will disable this
automatic power saving, but will **not** change the poll interval from its
current value. If you desire a specific interval (e.g. the default 80ms) you
must set it manually with `Bangle.setPollInterval(80)` after setting
`powerSave:false`.
* `lockTimeout` how many milliseconds before the screen locks
* `lcdPowerTimeout` how many milliseconds before the screen turns off
* `backlightTimeout` how many milliseconds before the screen's backlight turns
off
* `btnLoadTimeout` how many milliseconds does the home button have to be pressed
for before the clock is reloaded? 1500ms default, or 0 means never.
* `hrmPollInterval` set the requested poll interval (in milliseconds) for the
heart rate monitor. On Bangle.js 2 only 10,20,40,80,160,200 ms are supported,
and polling rate may not be exact. The algorithm's filtering is tuned for
20-40ms poll intervals, so higher/lower intervals may effect the reliability
of the BPM reading.
* `seaLevelPressure` (Bangle.js 2) Normally 1013.25 millibars - this is used for
calculating altitude with the pressure sensor
Where accelerations are used they are in internal units, where `8192 = 1g`

This behaves the same as the global `load()` function, but if fast
loading is possible (`Bangle.setUI` was called with a `remove` handler)
then instead of a complete reload, the `remove` handler will be
called and the new app will be loaded straight after with `eval`.
**This should only be used if the app being loaded also uses widgets**
(eg it contains a `Bangle.loadWidgets()` call).
`load()` is slower, but safer. As such, care should be taken
when using `Bangle.load()` with `Bangle.setUI({..., remove:...})`
as if your remove handler doesn't completely clean up after your app,
memory leaks or other issues could occur - see `Bangle.setUI` for more
information.

"ifdef" : "BANGLEJS",
"typescript": [
"showMenu(menu: Menu): MenuInstance;",
"showMenu(): void;"
]
}
Display a menu on the screen, and set up the buttons to navigate through it.
Supply an object containing menu items. When an item is selected, the function
it references will be executed. For example:
```
var boolean = false;
var number = 50;
// First menu
var mainmenu = {
"" : { title : "-- Main Menu --" }, // options
"LED On" : function() { LED1.set(); },
"LED Off" : function() { LED1.reset(); },
"Submenu" : function() { E.showMenu(submenu); },
"A Boolean" : {
value : boolean,
format : v => v?"On":"Off",
onchange : v => { boolean=v; }
},
"A Number" : {
value : number,
min:0,max:100,step:10,
onchange : v => { number=v; }
},
"Exit" : function() { E.showMenu(); }, // remove the menu
};
// Submenu
var submenu = {
"" : { title : "-- SubMenu --",
back : function() { E.showMenu(mainmenu); } },
"One" : undefined, // do nothing
"Two" : undefined // do nothing
};
// Actually display the menu
E.showMenu(mainmenu);
```
The menu will stay onscreen and active until explicitly removed, which you can
do by calling `E.showMenu()` without arguments.
See http://www.espruino.com/graphical_menu for more detailed information.
On Bangle.js there are a few additions over the standard `graphical_menu`:
* The options object can contain:
* `back : function() { }` - add a 'back' button, with the function called when
it is pressed
* `remove : function() { }` - add a handler function to be called when the
menu is removed
* (Bangle.js 2) `scroll : int` - an integer specifying how much the initial
menu should be scrolled by
* The object returned by `E.showMenu` contains:
* (Bangle.js 2) `scroller` - the object returned by `E.showScroller` -
`scroller.scroll` returns the amount the menu is currently scrolled by
* In the object specified for editable numbers:
* (Bangle.js 2) the `format` function is called with `format(value)` in the
main menu, `format(value,1)` when in a scrollable list, or `format(value,2)`
when in a popup window.
You can also specify menu items as an array (rather than an Object). This can be
useful if you have menu items with the same title, or you want to `push` menu
items onto an array:
```
var menu = [
{ title:"Something", onchange:function() { print("selected"); } },
{ title:"On or Off", value:false, onchange: v => print(v) },
{ title:"A Value", value:3, min:0, max:10, onchange: v => print(v) },
];
menu[""] = { title:"Hello" };
E.showMenu(menu);
```

"params" : [
["type","JsVar","The type of UI input: 'updown', 'leftright', 'clock', 'clockupdown' or undefined to cancel. Can also be an object (see below)"],

}
This puts Bangle.js into the specified UI input mode, and calls the callback
provided when there is user input.
Currently supported interface types are:
* 'updown' - UI input with upwards motion `cb(-1)`, downwards motion `cb(1)`,
and select `cb()`
* Bangle.js 1 uses BTN1/3 for up/down and BTN2 for select
* Bangle.js 2 uses touchscreen swipe up/down and tap
* 'leftright' - UI input with left motion `cb(-1)`, right motion `cb(1)`, and
select `cb()`
* Bangle.js 1 uses BTN1/3 for left/right and BTN2 for select
* Bangle.js 2 uses touchscreen swipe left/right and tap/BTN1 for select
* 'clock' - called for clocks. Sets `Bangle.CLOCK=1` and allows a button to
start the launcher
* Bangle.js 1 BTN2 starts the launcher
* Bangle.js 2 BTN1 starts the launcher
* 'clockupdown' - called for clocks. Sets `Bangle.CLOCK=1`, allows a button to
start the launcher, but also provides up/down functionality
* Bangle.js 1 BTN2 starts the launcher, BTN1/BTN3 call `cb(-1)` and `cb(1)`
* Bangle.js 2 BTN1 starts the launcher, touchscreen tap in top/bottom right
hand side calls `cb(-1)` and `cb(1)`
* `{mode:"custom", ...}` allows you to specify custom handlers for different
interactions. See below.
* `undefined` removes all user interaction code
While you could use setWatch/etc manually, the benefit here is that you don't
end up with multiple `setWatch` instances, and the actual input method (touch,
or buttons) is implemented dependent on the watch (Bangle.js 1 or 2)
**Note:** You can override this function in boot code to change the interaction
mode with the watch. For instance you could make all clocks start the launcher
with a swipe by using:
```
(function() {
var sui = Bangle.setUI;
Bangle.setUI = function(mode, cb) {
if (mode!="clock") return sui(mode,cb);
sui(); // clear
Bangle.CLOCK=1;
Bangle.swipeHandler = Bangle.showLauncher;
Bangle.on("swipe", Bangle.swipeHandler);
};
})();
```
The first argument can also be an object, in which case more options can be
specified:
```
Bangle.setUI({
mode : "custom",
back : function() {}, // optional - add a 'back' icon in top-left widget area and call this function when it is pressed , also call it when the hardware button is clicked (does not override btn if defined)
remove : function() {}, // optional - add a handler for when the UI should be removed (eg stop any intervals/timers here)
touch : function(n,e) {}, // optional - handler for 'touch' events
swipe : function(dir) {}, // optional - handler for 'swipe' events
drag : function(e) {}, // optional - handler for 'drag' events (Bangle.js 2 only)
btn : function(n) {}, // optional - handler for 'button' events (n==1 on Bangle.js 2, n==1/2/3 depending on button for Bangle.js 1)
clock : 0 // optional - if set the behavior of 'clock' mode is added (does not override btn if defined)
});
```
If `remove` is specified, `Bangle.showLauncher`, `Bangle.showClock`, `Bangle.load` and some apps
may choose to just call the `remove` function and then load a new app without resetting Bangle.js.
As a result, **if you specify 'remove' you should make sure you test that after calling `Bangle.setUI()`
without arguments your app is completely unloaded**, otherwise you may end up with memory leaks or
other issues when switching apps.
