f3e507ef9f New SWspanarrays attribs[] array. 
Replace texcoord[], varying[], etc. arrays with single attribs[] array, indexed
by FRAG_ATTRIB_* values.
Eliminates need to copy data into fragment program machine input registers.
Will lead to future clean-ups.

b63c100677 Overhaul handling of writemasks/swizzling. This fixes two problem cases: 
vec2 v;  v.x = v.y = 1.0;  // chained assignment
vec4 v;  v.zx = vec2(a,b);  // swizzled writemask
