Specs

transform_point(mat33(), vec2()) :: vec2()

transform_point( a, v ) transforms a vec2 point by a mat33.

a is a mat33 used to transform the point.

v is a vec2 to be transformed.

This returns a vec2 representing the application of a to v.

The point a is internally treated as having a third coordinate equal to 1.0.

Note that transforming a point will work for all transforms.
