minor edits / cleanup - no functional changes.

- use 'const float *' and array size in some function declarations.
- replace macros for BLI_math functions INPF, VECCOPY, VECADD etc.
- remove unused VertRen.clip struct member.
- remove static squared_dist() from 2 files, replace with BLI_math function len_squared_v3v3().
- use vertex arrays for drawing clipping background in the 3D viewport.
