This command controls the drawing of bitmaps: the on-screen size of the bitmap, the behavior for wrapping, and

the filtering function. Please note that if Wrapx or Wrapy is using REPEAT then the corresponding memory layout dimension

([[BitmapLayout]] linestride or height) must be power of two, otherwise the result is undefined.
