+/* 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;
+ * } 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;
+ * } 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];
+ * }
+ *
+ * HW_VIEWPORT: Hardware performs viewport transform.
+ * HW_DIVIDE: Hardware performs perspective divide.
+ *
+ * DO_XYZW: Emit xyz and maybe w coordinates.
+ * DO_RGBA: Emit color, v.color is in RGBA order.
+ * DO_BGRA: Emit color, v.color is in BGRA order.
+ * DO_SPEC: Emit specular color.
+ * DO_TEX0: Emit tex0 u,v coordinates.
+ * DO_TEX1: Emit tex1 u,v coordinates.
+ * DO_PTEX: Emit tex0, tex1 q coordinates where possible.
+ *
+ * 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.
