  CoglTexture* texture,
  int src_x,
  int src_y,
  int dst_x,
  int dst_y,
  unsigned int dst_width,

`dst_x`	`int`
	Upper left destination horizontal coordinate.
`dst_y`	`int`
	Upper left destination vertical coordinate.
`dst_width`	`unsigned int`
	Width of destination region to write. (Must be less than or equal to the bitmap width)
`dst_height`	`unsigned int`
	Height of destination region to write. (Must be less than or equal to the bitmap height)
`bitmap`	`CoglBitmap`
