GM_CreateCustomRasterLayer

Creates a new custom layer that represents an in-memory raster. The handle to the newly created layer is returned. You must call GM_CloseLayer on the returned handle when you are done with it. If a problem occurs, NULL is returned for the layer handle.

The layer handle returned can be used just like any other layer handle.
