Log:
[WIN32K]
- Switch from using a FONTDEV structure to using a PDEVOBJ (it was an idea to save half a
KB memory per driver, but it doesn't work well together with display drivers that
provide font capabilities)
- Modify EngLoadFontDriver to use PDEVOBJ_CreatePDEV instead of manually calling the
driver
- Implement RFONT_AllocRFONT, RFONT_vDeleteRFONT, RFONT_bQueryDeviceMetrics
