-/* 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];
- * }
- *
-
- * 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.
