Thanks for the clarification. I edited '1qt.cmake.in' in my copy of the
master branch to bundle all of the Qt image formats into a .app build [0].
It builds fine, with correct referencing to the bundled Qt frameworks.

Now, my help browser loads favicons and gifs [1], as well as rendering SVG
[2]. I ran into an issue where the browser would crash master whenever
there was an external website trying to load (not related to image
formats). So, I copied the extra image format .dylibs over to my local copy
of your 1.7.4 install, where they worked well, with no crashes from the
browser.

At only ~1.2 MB on disk, 400 KB compressed, is there any reason not to
include all of the image formats?
