Implemented QGLTextureGlyphCache to avoid wasting glyph cache memory.

Now there's only a copy of the texture glyph cache in graphics memory,
avoiding the system memory copy that we used earlier. In addition the
texture will use the GL_ALPHA texture format when possible, making it
consume less graphics memory as well.
