* p_tri_map_preprocessing
* -----------------------
* prepare the tri mask for processing
* - have bpp == 1
* - have same size and offset as the input drawable (that is a layer)
* - pixel values >= 240 are set to value 240 (MATTING_USER_FOREGROUND)
* - in case the input layer already has an alpha channel
* all fully transparent (alpha == 0) pixels are also set 0 (MATTING_USER_BACKGROUND)
* in the tri map to keep pixels fully transparent. (such pixels typicall do not
* have a useful color information in the RGB channels)
*
*
* in case the user provided the tri map as layer or channel that is NOT the layermask of the input layer
* we create a new dummy layer with same size and offset as the input layer
* and add a layermask to this dummy layer.
* The layermask of the dummy layer is then filled with the intersecting grayscale copy
* of the user-provided triMap drawable and will be used as tri map in the alpha matting processing.
*
* returns the dawable Id of the relevant TRI MAP that fulfills the conditons listed above.
