*	tgsi: add tgsi utility to transform a fragment shader to support aa point	Charmaine Lee	2015-09-01	1	-0/+309
	This adds a tgsi utility tgsi_add_aa_point to transform a fragment shader to support anti-aliased wide point by computing the fragment distance from the point center. This utility assumes the geometry shader is emitting an extra generic output with point coord data. The semantic index of this generic output is passed to the tgsi_add_aa_point utility.
