Detailed Description

subdivPlanarQuad.h: interface for the SubdivPlanarQuadS class.

A subdivided planar quad.
Currently 'primType' can ONLY be GL_QUADS.
(Need different indices generators for GL_TRIANGLES)
Lowerleft and upperRight are assumed to be in the XY plane
(only the x,y components are read). The quad is therefore always orthogonal to the Z axis with a normal = <0,0,1>
If 'genTexCoords' is true, but no 'altTexGen' is given, the ScaleTexGen2D texCoord generator is used. The 'altTexGen' parameter is used for alternate tex coord generation.
Generates a SINGLE primitive using vertex arrays and indices (hence the S in the name)
'sharedVerts' specifies if the shared-vertex or redundant-vertex subdiv quad is built.
Patch numbering begins at lower-left and reads right and then up
(OpenGL coord convention)
