a731c75442 port math function from Viewport FX 
mul_v4_m4v3(r, M, v) means r = M * vec4(v, 1.0)
Based on rB194998766c65

9bea012b8c specialize mat3 multiply routines 
Same as 5c6baf1ee9 but for 3x3 matrices.

5c6baf1ee9 specialize mat4 multiply routines 
mul_m4_m4m4(R, A, B) gives us R = AB in general. Existing code assumed the worst, that A and B both alias the output R. For safety it makes internal copies of A and B before calculating & writing R.

This is the least common case. Usually all 3 matrices differ. Often we see M = AM or M = MB, but never M = MM.

With this revision mul_m4_m4m4 is called in exactly the same way but copies inputs only when needed. If you know the inputs are independent of the output use the "uniq" variant to skip the saftety checks.

addc666999 constify BLI_math_matrix inputs 
GPU_matrix needs this very soon, and it's good practice in general.

also sprinkled in some TODOs for later

fbca69c69a BLI_math: add mat3_normalized_to_* functions 
Many uses of matrices for rotation keep them normalized,
so no need to normalize each time.

be72df4f06 BLI_math: add mat3_polar_decompose, interp_m3_m3m3 and interp_m4_m4m4. 
mat3_polar_decompose gives the right polar decomposition of given matrix,
as a pair (U, P) of matrices.

interp_m3_m3m3 uses that polar decomposition to perform a correct matrix interpolation,
even with non-uniformly scaled ones (where blend_m3_m3m3 would fail).

interp_m4_m4m4 just adds translation interpolation to the _m3 variant.

909fa34c5f BLI_matrix space_transform: Add a 'local-invariant' setter. 
`BLI_space_transform_from_matrices()` defines a 'global-invariant' transform
(same point in global space, two different coordinates in local and target spaces).

New `BLI_space_transform_global_from_matrices()` is kind of opposite, it defines
a 'local-invariant' transform (two different points in global space, same coordinates in local and target spaces).

Useful to 'match' meshes.

b6caefdaa9 Fix T43711: dual quaternion deform bug with shearing in deform matrix. 
This also increases the tolerances in is_orthogonal / is_orthonormal functions,
which were much too low for practical purposes.

af9da0be43 Complementary fix for rB8054372: Follow the common naming scheme by 
using negate_mat3_m4 instead of negate_m4.

This avoids changing the behavior and only flips the 3x3 part of the
matrix.

8489b94e07 Math Lib: rename mul_serie_m3 to mul_m3_series & reorder args

6f1f5771ff Correction to 7c7b730, multiplication order was flipped 
That's really annoying that multiplication order is flipped
comparing mat3 and mat4 cases, but for the purposes of not
breaking all the branches which might use this stuff we'd
better keep order consistent with old version for now.

Suggestion here would be to make order consistent but rename
this functions to mult_* to make compilation fail instead
of failing and using wrong order silently.

7f089afc8b Bake-API: relaxing in the check for scale uniformity 
It still warns the user that there may be an error, but the baking goes
on. Also using the new is_uniform_scaled_m4() instead of float comparison.

d4cc81d552 Fix T38870: Freezes when jumping in front of a keyframe. 
Issue was caused by inverting a degenerate matrix when
evaluating drivers.

Solved by using tweaked inverse code (same as used in Cycles).

Should have no affect on cases when matrix is not degenerate.
