Was it about blitting in general or surface_blt_to_drawable? Note that 
this routine isn't for blitting in the usual gdi or directx sense (as in 
from one bitmap or surface to another) - that code is in BltOverride. 
surface_blt_to_drawable is helper function for 
LoadLocation(...,INDRAWABLE,...) - which isn't supposed to be called for 
regular textures or offscreenplain surfaces.
