bb3efe6127 Blenlib: Assert when attempting to rotate point around vector and store result in the point 
This isn't supported since there are subsequent reads to all point coordinates
after modification started.

Probably we need to create a temp copy of point, but that's like extra CPU
ticks.

1d966ca7a1 Math Lib: add angle_on_axis_v3v3_v3 
Use for calculating the angle between 2 directions on an axis.

Also signed version and normalized plane projection,

1dbaf0dbcc Add mid_v3_v3_array function and remove redundant functions 
Other than implementing a `mid_v3_v3_array` function, this removes
`cent_tri_v3` and `cent_quad_v3` in favor of `mid_v3_v3v3v3` and
`mid_v3_v3v3v3v3` respectively.

82636ab0fb improved method of getting the tangent axis from a bmesh triangle, 
rather then getting the longest edge, get the edge which which is most different from the 2 others ends up giving more useful results: for an isosceles triangle it returns the base weather its longer or shorter then the other sides.

13254cde8c Alternate mask spline feather offset calculation method: now there are 2 [Even | Smooth] 
- Even preserves thickness but can give unsightly loops
- Smooth gives nicer shape but can give unsightly feather/spline mismatch for 'S' shapes created by beziers.

This is an example where smooth works much nicer.
