glamor: Concentrate and reduce some coords processing code.

Browse Source 
Concentrate the verties and texture coords processing code to a new
file glamor_utils.h. Change most of the code to macro. Will have some
performance benefit on slow machine. And reduce most of the duplicate
code when calculate the normalized coords.
