If you have the latest version of QRT (1.5) it will handle
arbitrary size bitmaps either with command line -xres and -yres switches
or with file keywords.  I've run up to 1024x1024 for display on
a workstation.  Also, if you received the complete system the
source code should be provided; it will compile under Lattice,
Manx, Un*x, and MS-DOS with no or trivial changes.  You can re-compile
it with whatever floating point options you wish and on whatever
mega-ultra-fast processor you wish.

Unfortunately QRT is more or less stagnant; I haven't touched it
in over a year, and I probably won't again.  If I do any more work
with graphics programs I will develop a new one from scratch which
overcomes some of the shortcomings of QRT.  However I have several
other projects with a higher priority right now, so don't hold your
breath :-)

Sorry.
