image re-project now uses offscreen render function and has input for render size.

unrelated changes that ended up being more trouble to commit separate...

- removed BLI_split_dirfile(), was nasty, occasionaly modifying the source string, it could create directories and used the $CWD in some cases. was only used in 2 places in filesel.c, if this gives problems can address without bringing back this function.
  renamed BLI_split_dirfile_basic --> BLI_split_dirfile

- view3d_operator_needs_opengl was being called for offscreen render when it wasnt needed.
