What steps will reproduce the problem?
1. run examples/collidepoly.py
2. drag the paralellogram so the bottom right corner touches the slanted side 
of the triangle around the middle.
3. watch the square make big jumps left or up instead of moving a slight bit 
diagonal

What is the expected output? What do you see instead?
I expect the parallelogram to move along the normal of the slanted face. 
instead it moves left or up.

What version of the product are you using? On what operating system?
irrelevant

Please provide any additional information below.

it seems having the square collide with the triangle forgets to use the slanted 
edge of the triangle. when using SAT you need to take into accounts the axises 
of *both* polygons.
