cliprect : pointer to a rectangle structue which describes the visible area of the target bitmap
line_pos : scanline render position relative to the target bitmap
should be a Y offset to the target bitmap in normal orientaion,
or an X offset to the target bitmap if X,Y are swapped
scroll : source scroll value of the scanline
zoom : source zoom factor of the scanline
src_clipmask : source offset clip mask; source pixels with offsets beyond the scope of this mask will not be drawn
src_wrapmask : source offset wrap mask; wraps source offset around, no effect when src_clipmask is set
orientation : flags indicating whether scanlines should be drawn horizontally, vertically, forward or backward
priority : value to be written to the priority bitmap, no effect when equals zero

cliprect : pointer to a rectangle structue which describes the visible area of the target bitmap
line_pos : scanline render position relative to the target bitmap
should be a Y offset to the target bitmap in normal orientaion,
or an X offset to the target bitmap if X,Y are swapped
scroll : source scroll value of the scanline
zoom : source zoom factor of the scanline
src_clipmask : source offset clip mask; source pixels with offsets beyond the scope of this mask will not be drawn
src_wrapmask : source offset wrap mask; wraps source offset around, no effect when src_clipmask is set
orientation : flags indicating whether scanlines should be drawn horizontally, vertically, forward or backward
priority : value to be written to the priority bitmap, no effect when equals zero
