[win32] reflected changes to canvas surface interface on GL backend. But implementation still uses the (slower) Loop-Blinn + triangle fan method.

[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.

[Clean canvas/shaders]
...
- Simplified shader names, prefix embedded strings by "glsl_"
- Extracted shader compilation in common function
- Add shader version string and common structs in canvas code rather than in every shader file
- Renamed zIndex with shapeIndex everywhere

- Move and Zoom perf_text example with the mouse
...
- Reverted to using 4 bits of subpixel precision and computing cross products with 32 bits integers, for perf reasons
- Fixed some confusion in tile array size vs number of elements (could still clean-up naming a bit though)
- Fixed bug where triangles on the left or below canvas boundaries where bucketted to the first colum/row of tiles
- Fixed bug in mouse button message handling (was always sending press on left button)

opengl surface/renderer: set surface scaling according to dpi of first monitor. Use that dpi to scale backing texture of canvas renderer. Note: changing monitor isn't handled yet!
