Description Fujii Hironori 2022-09-12 21:31:09 PDT 
TransformationMatrix: mapPoint, mapRect and mapQuad should clamp a point at infinity such as projectPoint

If w<0, the point is at infinity. projectPoint clamps such points.
mapPoint, mapRect and mapQuad also should do that.

TextureMapper has problems due to this bug (bug#244824 and bug#244915 comment#2).
