/* Unlike the other templates here, this assumes quite a bit about the
* underlying hardware. Specifically it assumes a d3d-like vertex
* format, with a layout more or less constrained to look like the
* following:
*
* union {
* struct {
* float x, y, z, w;
* struct { char r, g, b, a; } color;
* struct { char r, g, b, fog; } spec;
* float u0, v0;
* float u1, v1;
* float u2, v2;
* float u3, v3;
* } v;
* struct {
* float x, y, z, w;
* struct { char r, g, b, a; } color;
* struct { char r, g, b, fog; } spec;
* float u0, v0, q0;
* float u1, v1, q1;
* float u2, v2, q2;
* float u3, v3, q3;
* } pv;
* struct {
* float x, y, z;
* struct { char r, g, b, a; } color;
* } tv;
* float f[16];
* unsigned int ui[16];
* unsigned char ub4[4][16];
* }
*
* VERTEX: hw vertex type as above
* VERTEX_COLOR: hw color struct type in VERTEX
*
* DO_XYZW: Emit xyz and maybe w coordinates.
* DO_RGBA: Emit color.
* DO_SPEC: Emit specular color.
* DO_FOG: Emit fog coordinate in specular alpha.
* DO_TEX0: Emit tex0 u,v coordinates.
* DO_TEX1: Emit tex1 u,v coordinates.
* DO_TEX2: Emit tex2 u,v coordinates.
* DO_TEX3: Emit tex3 u,v coordinates.
* DO_PTEX: Emit tex0,1,2,3 q coordinates where possible.
*
* HAVE_RGBA_COLOR: Hardware takes color in rgba order (else bgra).
*
* HAVE_HW_VIEWPORT: Hardware performs viewport transform.
* HAVE_HW_DIVIDE: Hardware performs perspective divide.
*
* HAVE_TINY_VERTICES: Hardware understands v.tv format.
* HAVE_PTEX_VERTICES: Hardware understands v.pv format.
* HAVE_NOTEX_VERTICES: Hardware understands v.v format with texcount 0.
*
* Additionally, this template assumes it is emitting *transformed*
* vertices; the modifications to emit untransformed vertices (ie. to
* t&l hardware) are probably too great to cooexist with the code
* already in this file.
*
* NOTE: The PTEX vertex format always includes TEX0 and TEX1, even if
* only TEX0 is enabled, in order to maintain a vertex size which is
* an exact number of quadwords.
