Speedup for font drawing, every letter was character was calling:

  glGetIntegerv(GL_TEXTURE_2D_BINDING_EXT, &cur_tex);

... with shadow enabled glGetFloatv(GL_CURRENT_COLOR, color) was called twice per character as well.


Now only call glGetFloatv(GL_CURRENT_COLOR, ...) once per string and only when drawing with shadow or blur, texture bind is stored in the font.

Gives 8% overall FPS speedup when displaying heavy UI in my test.
