i see what you mean.

OpenGL CAN compensate all this, see glPixelStore. you can specify  
alignment and row length and some other properties of pixel memory.

But will you ever get aligned array when using sdl_ttf? I'm using it  
with OpenGL and i just use surface->w and surface->h and everything  
looks fine with different fonts and font sizes etc.
