Now all the fine-tuning is happening using parallel range settings structure,
which avoid passing long lists of arguments, allows extend fine-tuning further,
avoid having lots of various functions which basically does the same thing.
yet another bug introduced by recent shadowing changes -- q and r CCG arrays
were overwritten by the temporary evaluation because the code was changed to
use global pointers instead of the local ones.
Naming of the variables could be changed to be a bit more accurate.
This is a preparation commit for having OpenSubdiv integrated into Blender
and new layout is the following:
- CCGSubSurf.c contains implementation of common functions used by both
legacy subdivisions code and by the new code in the future.
- CCGSubSurf_inline.h contains internal functions which are to be inlined
due to the performance reasons. Those functions are only ment to be used
bu CCGSubSurf* files.
- CCGSubSurf_intern.h contains declarations of private functions and data
structures used by CCGSubSurf module.
- CCGSubSurf_legacy.c contains legacy implementation of subdivision algorithm.
- CCHSubSurf_util.c contains utility functions which are not directly related
on the subdivision code (i.e. debug functions, hash implementation etc).
There should be no functional changes so far.
