  2792. Block Transfer Move
  2793. Can move a rectangular block from any area of memory (eg. layer 1) to any other (eg layer 2)
  2794. Can move with transparency - note THE TRANSPARENT COLOUR IS THE TEXT FOREGROUND COLOUR
  2795. ReverseDir is for moving overlapping areas - may need to use reverse to prevent it double-copying the overlapping area (this option not available with transparency or monochrome)
  2796. ROP is Raster Operation. Usually use RA8875_ROP_SOURCE but a few others are defined
  2797. Defaults to current layer if not given or layer is zero.
  2798. Monochrome uses the colour-expansion mode: the input is a bit map which is then converted to the current foreground and background colours, transparent background is optional
  2799. Monochrome data is assumed to be linear, originally written to the screen memory in 16-bit chunks with drawPixels().
  2800. Monochrome mode uses the ROP to define the offset of the first image bit within the first byte. This also depends on the width of the block you are trying to display.
  2801. Monochrome skips 16-bit words in the input pattern - see the example for more explanation and a trick to interleave 2 characters in the space of one.
  2802. This function returns immediately but the actual transfer can take some time
  2803. Caller should check the busy status before issuing any more RS8875 commands.
  2804. Basic usage:
  2805. BTE_Move(SourceX, SourceY, Width, Height, DestX, DestY) = copy something visible on the current layer
  2806. BTE_Move(SourceX, SourceY, Width, Height, DestX, DestY, 2) = copy something from layer 2 to the current layer
  2807. BTE_Move(SourceX, SourceY, Width, Height, DestX, DestY, 2, 1, true) = copy from layer 2 to layer 1, with the transparency option
  2808. BTE_Move(SourceX, SourceY, Width, Height, DestX, DestY, 0, 0, true, RA8875_BTEROP_ADD) = copy on the current layer, using transparency and the ADD/brighter operation
  2809. BTE_Move(SourceX, SourceY, Width, Height, DestX, DestY, 0, 0, false, RA8875_BTEROP_SOURCE, false, true) = copy on the current layer using the reverse direction option for overlapping areas
