Is there any way to have the external tool QML Preview take on a different

I guess you're talking about qmlscene (the tool for Qt Quick 2): There's AFAIK
no way to force a specific size from the command line, but you can play with
the options

If you run your code with QSG_INFO=1 in the environment, does it report how
many samples it finds? (16 is usually the absolute max on desktop hardware, 8

FYI, I did some experiments here, and as I suspected, none of the *_p.c files
have to be compiled in and can thus be removed. If these files caused a problem
for you, just remove them from the list of SOURCES in iaccessible2.pri.
FYI, I have prepared a patch here that removes the uneeded files.
