@hoffstadt new or old! personally i think the pl_gjk_ext.* is the way to go.....I know we talked about the method in _old. but

• i don't think it scales well, seeing as with the newer way users can define their own support functions (benefit of gjk)
• the new method reuses shapes already defined in pl_math, instead of users having to copy over into our defined plShape struct with a type......seems like a waste of time
• the union of shapes also made for huge mismatches in struct size between something liek a sphere, and something like a frustum
