max - Maximum

max     dest, src0, src1

Name	Registers
dest	An output register or temporary register.
src0	A temporary register, input register, or floating-point constant register.
src1	A temporary register, input register, or floating-point constant register.

You cannot specify a floating-point constant register for both src0 and src1.
You cannot specify input registers using different indices for src0 and src1 at the same time.

Compares src0 and src1 and then stores the larger value in dest.

dest.x = ( src0.x > src1.x ) ? src0.x : src1.x
dest.y = ( src0.y > src1.y ) ? src0.y : src1.y
dest.z = ( src0.z > src1.z ) ? src0.z : src1.z
dest.w = ( src0.w > src1.w ) ? src0.w : src1.w
