Follow-up Comment #14, bug #27782 (project gnustep):
I figured out why NSCopyBits was drawing at the wrong location when the
destination is rotated. An updated patch is attached.
In -compositeGState, the pattern matrix was set up like that:
cairo_matrix_translate(&source_matrix, minx - x - dx, miny - y - dy -
ssize.height);
when it should have been:
cairo_matrix_translate(&source_matrix, minx - x + dx, miny - y + dy -
ssize.height);
(file #20255)
