======= Function 25 - put image area on the background layer. ========
======================================================================
Paramters:
* eax = 25 - function number
* ebx = pointer to the previously allocated memory area,
where placed the source images in a format BBGGRRTTBBGGRRTT...
* ecx = [size on axis x]*65536 + [size on axis y]
* edx = [coordinate on axis x]*65536 + [coordinate on axis y]
Returned value:
* function does not return value
Remarks:
* Coordinates of the image are coordinates of the upper left corner
of the image relative to the screen.
* Size of the image in bytes is 4*xsize*ysize
* TT - byte pointer of transparency, at current version:
1 to FF - opaque, 0 - transparent.
* The function places the image directly to LFB. It is not for
background image f.15. Options f.15 to f.25 does not make sense.
