[canvas] decompose image atlas API into simple rect atlas API + image atlas helpers. This avoids creating a bunch of new types/handles, and exposes the underlying image/sourceRegion so that user code can freely use these for more complex scenarios (eg drawing only a sub-region of an atlased image, or using an atlas image for arbitrary path filling)

Use a custom GL loader to allow different versions of GL/GLES APIs to co-exist. The loader fills an api struct with GL functions pointers.
...
We have a per-thread pointer to select which api struct is used, and GL functions are pound-defined to call the versions in that struct.
GL/GLES surfaces can use one of the loader function to load their api, and the prepare proc of the surface sets its api as the current one
before gl calls are issued.
