CCleaner 3.04.1389 properly draws bitmaps on buttons when we are unthemed, but does not draw them when we are themed

ros 0.4.8-dev-792 gcc dbg.

Use CCleaner 3.04.1389 ccsetup304.exe (do not use the newer version from rapps)
When we are unthemed, the app can properly draw the bitmaps on its buttons, but does not draw them when we are themed. see ccleaner.webm

0.4.8-dev-792.log

ccleaner-regressionTest.txt does not help much.
