I agree.

Agreed, again.  The code already handles this case.  It checks for the
presence of the jp2k Qt image format plugin, and only then will it
attempt to decode the larger sized representations of the icon.

That's how I'm imagining it working as well.  No 3rdparty source tree
needs to be bundled (it isn't bundled in qt-solutions either, at the
moment) - but link against the JasPer lib if it's present on the
system, or JASPER_CFLAGS and JASPER_LIBS are specified to configure
(or however we want it to function).
