New Procedures and Functions
GLuint CreateImageCHROMIUM(ClientBuffer buffer,
GLsizei width,
GLsizei height,
GLenum internalformat)
Create an image from <buffer> with width equal to <width> and
height equal to <height> and format equal to <internalformat>.
Returns a unique identifier for the image that could be used in
subsequent operations.
INVALID_VALUE is generated if <width> or <height> is nonpositive.
INVALID_ENUM is generated if <internalformat> is not one of
RGB, RGBA or GL_BGRA_EXT.
void DestroyImageCHROMIUM(GLuint image_id)
Frees the image previously created by a call to CreateImageCHROMIUM.
INVALID_OPERATION is generated if <image_id> is not a valid image id.

If EXT_texture_format_BGRA8888 is not supported:
* delete any reference to the GL_BGRA_EXT format.
Errors
