I need this now especially as it gets us the shader modification mechanisms to work around Mac GL crashes, see bug 665578
The relevant ANGLE revisions are 734, 738, and 740 fixes a bug in 738.
This also allows us to reset our set of cherrypicked ANGLE revisions which was starting to be very big.
TiledTextureImage breaks BeginUpdate/EndUpdate in these cases:
- The update is encompassed by more than one tile
- The update is encompassed by a single tile that isn't the first tile
- The update is a non-rectangular region that covers more than one tile
Fixed by using signed instead of unsigned integers in tile loops, correcting
an incorrect device offset and correcting the region returned by BeginUpdate.
Although we currently have buffer rotation disabled for shadow buffers when
using the GL layer manager, if you re-enable it, it will be broken. This is
because we don't take into account the rotation when handling updates.
This fixes that handling by offsetting the updated region by the rotation,
and if that new region crosses texture boundaries, splitting it into
multiple uploads.
Drawing of rotated buffers relies on texture-wrapping, but in the case of
tiled textures, this would cause each individual tile to wrap instead of
wrapping the compound texture.
Add a special case for tiled textures that manually does the wrapping.
Currently fixup_unbounded_boxes assumes that the extents are tight when we only
have one box. This is not always true. e.g. when we tesselate boxes we can end
up with only one box which is smaller than the extents and the extents are not
updated.

should never happen).

Cairo requires image surfaces to have a particular stride alignment.
Sometimes the texture we get back from Direct3D doesn't meet these
requirements. In that case, copy to a different buffer that meets
these requirments.

This changes the only remaining callers (in nsMathMLChar) to pass the
correct language, which they were not previously doing, which should
improve the correctness of font selection and also reduce the number of
unique font metrics objects requested (which helps nsFontCache
effectiveness). Those callers, however, remain the odd font users
within all of layout.
