void glClear(GLbitfield mask)

NOP: there's nothing to clear on the PVR2. Provided to ease porting.

void glClearColor(GLclampf red, GLclampf green, GLclampf blue, GLclampf alpha)

Sets the background color. Alpha parameter has no effect.

void glCullFace(GLenum mode)

Set face culling mode. Valid states are GL_FRONT and GL_BACK. Default state is GL_BACK.

void glDisable(GLenum cap)

Disable GL states. See table in section , on page .

void glEnable(GLenum cap)

Enable GL states.

State	Description / Notes	Initial Value
GL_BLEND	NOP: will be available once the PVR scene rendering API is completed. For now use glKosFinishList() to switch to the transparent polygon list.	GL_FALSE
GL_CULL_FACE	Polygon culling	GL_FALSE
GL_FOG	PVR table fog	GL_FALSE
GL_KOS_AUTO_UV	Automatically assign texture coordinates to GL_QUAD primatives.	GL_FALSE
GL_KOS_USERCLIP_OUTSIDE	Drawn polys are clipped to the outside of the scissor box.	GL_FALSE
GL_SCISSIOR_TEST	Drawn polys are clipped to the inside of the the scissor box.	GL_FALSE
GL_TEXTURE_2D	2D texturing	GL_FALSE

void glFrontFace(GLenum mode)

Set polygon front face. Valid modes are GL_CW and GL_CCW. Default mode is GL_CCW. Note: In KGL prior to KOS-1.1.7 the default was GL_CW and could not be changed.

void glFlush()

NOP: There is no rendering pipeline.

void glHint(GLenum target, GLenum mode)

NOP: It's our way or no way. KGL_DONT_CARE =D Provided to ease porting.
