qemu command line to specify "vram":
-global qxl.vram_size=uint
qemu command line to specify "heads", (no need of '-device' for
the first 'head'):
-device qxl,id=qxl-N (N is natural number)
This patch is just about the command line building, still left work
on the command line parsing (hacking on "qemuBuildCommandLine"), as
I'm even not sure if it's the right way to build the command line.
Any advise/idea is appreciated.
