strong

When we transform points through a matrix containing perspective (the bottom row is something other than 0,0,1), the bruteforce math can produce confusing results (since we might divide by 0, or a negative w value).

By default, methods that map rects and paths will apply perspective clipping, but this can be changed by specifying kYes to those methods.

Enumerator
kNo	Don't pre-clip the geometry before applying the (perspective) matrix.
kYes	Do pre-clip the geometry before applying the (perspective) matrix.
