test/source/blender/src/drawimage.c
Campbell Barton 2a331067cc resolve some compiler warnings with intel c/c++ compiler 
* subsurf code had a lot of unused variables, removed these where they are obviously not needed. commented if they could be useful later.
* some variables declorations hide existing variables (many of these left), but fixed some that could cause confusion.
* removed unused vars
* obscure python memory leak with colorband.
* make_sample_tables had a loop running wasnt used.
* if 0'd functions in arithb.c that are not used yet.
* made many functions static
