Add work around for bug when painting w/glTexSubImage into large texture
It seems that copying small rectangles from glTexSubImage2D into a
texture which is 2048x2048 is busted on some SGX drivers, even though
the driver reports 2048 as the maximum texture size. This caused text to
turn into flickering garbage once the texture glyph cache had grown to
its max size (e.g. when painting very many Chinese glyphs.) To work
around the problem, we hardcore the maximum texture height to 1024 on
this driver so that the texture glyph cache is reset whenever that
size is exceeded.
