This allows binding to a multisampled framebuffer, useful for drawing 3D content with MetalNanoVG. Example: ``` id renderTargetTexture; // Texture where sampleCount > 1 NVGcontext *nvg; ... MNVGframebuffer framebuffer; framebuffer.ctx...

Sensor input is implemented on iOS and Android, but not for Web. Sensors: accelerometer, magnetometer, gyroscope, rotation matrix To implement in `glfm_platform_emscripten.c`: * `glfmIsSensorAvailable` * `_glfmSensorFuncUpdated` (enable/disable sensors as needed)...

This should improve key events. Also, look into GCMouse https://developer.apple.com/documentation/gamecontroller?language=objc

Also, make the GLFM AppDelegate optional.
