I like your patch, and I guess it'll always be faster on a machine with
no FPU, of course there are a number of other places where this should
be used.
Having something like:
enum {
MATRIX_CORE_IS_UNIT = 0,
MATRIX_CORE_IS_PURE_SCALE = 1,
MATRIX_HAS_TRANSLATE = 0x800
} MatrixProp;
Or whatever,
That was tracked, and used to annotate the various matrix operations
might be fast & small enough for both use-cases; might also accelerate
some other cases: general matrix products etc.
HTH,
Michael.
