Swap postions of "OK" and "Cancel" buttons?

My boss wants me to move the couch... err, to swap the positions of the "Ok" and "Cancel" buttons where they appear (such as in the image and link popups).

One thing I did was to disable the "Upload" tabs in both of these popups - that wasn't an issue, as the relevent code was within each function's .js files, just a matter of commenting it out - but the Ok/Cancel buttons seem to be more universal, and I have yet to sniff out the spot in the codebase that governs the order that these buttons are displayed.

Running under 3.2.1.

Thanks in advance -
