f32: add Affine2D.Split
...
splitTransform func was creating multiple copies of f32.Affine2D
due to not having access to the internal and passing around non-pointer.
This makes splitTransform from ~8ns to .Split ~2ns.
It seems that the non-pointer receiver was ~0.6ns slower in this case.

f32: optimize Affine2D
...
encode/decode seem to introduce significant overhead. Inline them
manually. It'll make code harder to read, however the performance wins
are significant.

f32: implement 2D affine transformations
...
Implements 2D affine transformations. This commit is a step
towards full affine transformations for drawing operations.
Heavily based on the work by Péter Szilágyi in patch 9212
