Follow-up Comment #7:
@Pantxo: I dumped all of the demos and compared them pre/post patch. It
doesn't seem that anything is drawn incorrectly. Also, I ran 'make check' and
all tests still pass.
If I understand the patch correctly, draw_image in gl-render.cc became much
simpler, but draw_image in gl2ps-print.cc became much more complicated.
I would have thought using textures over gl2psDrawPixels would have been
slower, but it seems not to be. I tested with a 10MB image and display times
as caluclated by
tic; imshow (img); toc
were the same.
Printing to a vector format like PDF leaves some weird pixels behind, but
these are cleaned up if the image is resized which forces a re-paint. It
would be nice to clean that up at some point.
Sample code
demo image 1
print tst.pdf
