Fixed text rendering on GL ES 2 implementations.
Some GL ES 2 implementations seem to have problems with
glCopyTexSubImage2D(), so we fall back and read the old font texture
into system memory and re-upload the new font texture.
Also, the precision used for texture coordinates in the fragment
programs wasn't high enough, which could lead to rendering artifacts.
