 /* Interface history:
  *
···
  * 1.11- Add packet R200_EMIT_RB3D_BLENDCOLOR to support GL_EXT_blend_color
  *       and GL_EXT_blend_[func|equation]_separate on r200
  * 1.12- Add R300 CP microcode support - this just loads the CP on r300
- *       (No 3D support yet - just microcode loading)
+ *       (No 3D support yet - just microcode loading).
  * 1.13- Add packet R200_EMIT_TCL_POINT_SPRITE_CNTL for ARB_point_parameters
  *     - Add hyperz support, add hyperz flags to clear ioctl.
  * 1.14- Add support for color tiling
···
  *       R200_EMIT_PP_TXFILTER_0-5, 2 more regs) and R200_EMIT_ATF_TFACTOR
  *       (replaces R200_EMIT_TFACTOR_0 (8 consts instead of 6)
  * 1.19- Add support for gart table in FB memory and PCIE r300
