trunk: clip-path of clipped group incorrectly scaled when changing default units (rev >= 12554)

Sample file with masked instead of clipped groups.

confirmed on Inkscape rev 13107

Reproduced with r13493 (inkscape-trunk PPA) on Ubuntu 14.04 (VM, 64bit; host: OS X 10.7.5).

Seems to be fix by mathog's changes in r13544:
<http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/13544>
 (reproduced with r13543, not reproduced with r13545 using the two test cases attached to the report)

Can others confirm, or are possibly aware of test cases not yet fixed? See also:
<http://thread.gmane.org/gmane.comp.graphics.inkscape.devel/44323>

r13549 removes this fix but leaves it intact for #1287288. For discussion of why I had to take it back out see <http://thread.gmane.org/gmane.comp.graphics.inkscape.devel/44323>

fix committed to rev 13561

the necessary transform is applied directly to the clip or mask in the defs section

I'm not sure that this is a correct fix. If two items refer to the same clippath won't the transform be done twice? Also, what if an item is both clipped and masked?

I've started looking into a similar problem with <use> that points to a <symbol> inside a <defs> section..

>> If two items refer to the same clippath won't the transform be done twice? Also, what if an item is both clipped and masked?

good questions. with respect to the first question I don't know what would happen. I have not been able to produce an example that illustrates that point.

wrt the second question, attached is a file that illustrates the problem. The example fails after the unit change. However I think the fix for this should be relatively simple, and I will investigate it tonight. If there is no objection, I will commit a proposed solution today or tomorrow, if I find one.

improved version committed to rev 13562, to allow for the case where a group contains both a clip and a mask
