NAME

	CreateBehindLayer -- Create a new layer behind all existing layers.

SYNOPSIS

	result = CreateBehindLayer(li,bm,x0,y0,x1,y1,flags [,bm2])
	d0                         a0 a1 d0 d1 d2 d3   d4  [ a2 ]
	struct Layer *CreateBehindLayer(struct Layer_Info *, struct BitMap *,
	    LONG, LONG, LONG, LONG, LONG, ... );

FUNCTION

	Create a new Layer of position and size (x0,y0)->(x1,y1)
	Make this layer of type found in flags.
	If SuperBitMap, use bm2 as pointer to real SuperBitMap,
	and copy contents of Superbitmap into display layer.
	If this layer is a backdrop layer then place it behind all
	other layers including other backdrop layers. If this is
	not a backdrop layer then place it behind all nonbackdrop
	layers.
	Note: when using SUPERBITMAP, you should also set LAYERSMART flag.

INPUTS

	li - pointer to LayerInfo structure
	bm - pointer to common BitMap used by all Layers
	x0,y0 - upper left hand corner of layer
	x1,y1 - lower right hand corner of layer
	flags - various types of layers supported as bit sets.
	        (for bit definitions, see graphics/layers.h )
	bm2 - pointer to optional Super BitMap

RESULT

	result - pointer to Layer structure if successful
	         NULL if not successful
