Usage:
vga="qxl"
Qxl vga support many resolutions that not supported by stdvga,
mainly the 16:9 ones and other high up to 2560x1600.
With QXL you can get improved performance and smooth video also
with high resolutions and high quality.
Require their drivers installed in the domU and spice used
otherwise act as a simple stdvga.

Changes in v16:
- refresh
- improved commit description
Changes in v15:
- refresh
- small code improvements in libxl_dm.c
Changes in v14:
- refresh
- update qemu parameters (from -vga to -device)
NOTES:
Works correctly with windows domUs, tested on windows 7 64 bit
with qxl driver from spice guest tools 0.74.
I tested some resolution not supported by stdvga (1366x768, 1600x900
and 1920x1080) with 32 bit color and all works good equal to kvm.
For now not works on linux domUs when xorg have 100% cpu and black
screen with qxl driver installed.
Seems needed other changes/fixes on xen and/or xorg/qxl driver side
before have it full working with linux domUs.
