Resolves: tdf#95962 incorrect scanline stride

we were reusing the stride of the surface we were cloning,
but the new surface has a different underlying size.

remove the custom stride argument and just change our stride
calculation to use the same scheme that cairo and GDI uses, which
remove another platform/drawing-system variable
