 				Clears the specified [param texture] by replacing all of its pixels with the specified [param color]. [param base_mipmap] and [param mipmap_count] determine which mipmaps of the texture are affected by this clear operation, while [param base_layer] and [param layer_count] determine which layers of a 3D texture (or texture array) are affected by this clear operation. For 2D textures (which only have one layer by design), [param base_layer] and [param layer_count] must both be [code]0[/code].
 				[b]Note:[/b] [param texture] can't be cleared while a draw list that uses it as part of a framebuffer is being created. Ensure the draw list is finalized (and that the color/depth texture using it is not set to [constant FINAL_ACTION_CONTINUE]) to clear this texture.
