Fix SVG flip when svg.image_noscale is True

[dmcdougall]

Fixes #1673.

Not sure if this is the correct solution, but it appears to work for me, and all the tests pass locally with py27.

Thanks! It worked for me. Since the line h,w = im.get_size_out() appears right after the if clause, it seems better to move the line above the if clause and delete the one after the if clause.

[dmcdougall]

@tkanmae Yes, you are correct. I will move it. Thank you.

[dmcdougall]

I rebased so as not to create an unnecessary commit.

Looks good to me. I wonder if we should add an image comparison test for the noscale case.

[dmcdougall]

Hm, moving the im.get_size_out() line above the if broke the output. I'll look into this...

[dmcdougall]

@tkanmae So, there is a call to im.resize(numcols, numrows) at the end of the if block what messes with w, h, so I had to put it back. It works now.

[tkanmae]

Sorry, I missed the point. Hope it will soon get merged.

Great work for a pretty serious bug. @dmcdougall : Like the new avatar, btw.
