2.5:

* Windows fixes for texture filter & bump patches, thanks
  Jean-Michel Soler for noting.

* Added sqrtf/sinf/fabsf/... fallback #ifdefs in BLI_arithb.h,
  those should be safe to use now. Replacing the double for the
  float version throughout the code can be done once, but would
  need proper testing.
