in gl-react: the context no longer have {width,height} but have {glSizable} which is an object with a getGLSize function. the size is dynamically calculated in the graph & using gl.drawingBufferWidth / gl.drawingBufferHeight which allows more flexible implementations.
in gl-react-dom: nothing fundamentally changes
in gl-react-native/exponent: Surface no longer takes width/height props! instead, it is just the style object, like any usual React Native view. e.g. you can use flexbox!
