Ash Logan ed24d05752 WiiU: gfx_display: fix non-vertex coordinates in draws using tex shader
This second case is hit when there's a quad with different-coloured 
corners, since the tex shader is needed to support that. In the quad 
case, there are no vertexes, and the ->x,y,width,height fields are used 
instead.

Fixes #8519.
