Fix floating point precision loss in renderer [part 2]

Fix floatTime using float precision instead of double using GCC.
Fix R_BindAnimatedImage to be in sync with function table.
Fix vertexDeform bulge, vertexDeform normals, noise wave function
at high level time.

Revert unnecessary float -> double conversions.
