NAME

	CreateUpfrontLayer -- Create a new layer on top of existing layers.

SYNOPSIS

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

FUNCTION

	Create a new Layer of position and size (x0,y0)->(x1,y1)
	and place it on top of all other layers.
	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.
	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.
	bm2 - pointer to optional Super BitMap
