This fix works in both GLES3 and GLES2.
The rendering formula in the shader was adjusted to further improve the
sharpness/antialiasing quality balance.

On some hardware, modifying gl_FragColor multiple times can cause large performance drops. This PR writes to a standard temporary variable instead, and copies across to gl_FragColor once only at the end of the fragment shader.
This could potentially lead to large gains in performance on affected hardware.
Certain glGet operations require 64 bit versions according to the GLES spec.
The previous code was susceptible to overflow bugs, especially running under ANGLE.
`-Werror=array-bounds` flags when creating a new batch, possibly due to the possibility of the malloc failing (out of memory).
This PR adds an explicit `CRASHNOW` in the hope the compiler will recognise this case is not intended to be recoverable.
Make sure `GLWrapper` is initialized before `glActiveTexture` is called by other parts of the storage initialize(), to prevent benign warnings.

Although this check shouldn't be able to fail currently, it provides a small level of extra logic checking at only small cost in DEV builds.

Adds optional hierarchical culling to the 2D rendering (within VisualServer).
Each canvas item maintains a bound in local space of the item itself and all child / grandchild items. This allows branches to be culled at once when they don't intersect a viewport.

Large groups of similar rects can be processed more efficiently using the MultiRect command. Processing common to the group can be done as a one off, instead of per rect.
Adds the new API to VisualServerCanvas, and uses the new functionality from Font, BitmapFont, DynamicFont and TileMap, via the VisualServerCanvasHelper class.
