x0: LongInt;

y0: LongInt;

x1: LongInt;

Arguments

`x0`		left corner of layer
`y0`		upper corner of layer
`x1`		right corner of layer
`y1`		lower corner of layer

pointer to Layer structure if successful nil if not successful

Arguments

`x0`		left corner of layer

`y1`		lower corner of layer
`Flags`		various types of layers supported as bit sets. Flags: LAYER*

Description

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.

Attention

When using bm2 SuperBitmap, you should also set LAYERSMART flag.
