BMesh Decimate: use doubles to calculate optimized position
...
This allows the error threshold for calculating the optimized location to be much lower.
Resolves visible artifacts w/ 1m-tri happy-buddha example.

Fix T44780: Decimate planar creates concave edges
...
Float precision was causing problems for decimate,
small faces that create a nearly flat surface were detected as having no 'cost' to collapse.

BMesh: decimate wasn't using face/edge centers
...
When calculating quadrics, using the first-vertex isn't correct.

fix [ #33106 ] Decimate modifier/collapse give bad result
...
FLT_EPSILON was too small to use when checking if the edge collapse result is an error.
add invert_m3_m3_ex(), invert_m3_ex() functiosn which take an epsilon to check the determinant, saves calculating it twice per edge collapse.
