- Started the use of DC_ATTR. Created dcutil.c to handle xfers. I choose XForms this time and still trouble shooting it. If anyone wants to join in and help. Optimize syncing the data packets, add more, etc. Don't be shy!

- Removed NtGdiGetWorldTransform from w32ksvc.db and updated ntgdibad.h.
- Implemented GetTransform redirect to NtGdiGetTransform.
- Connected the gdi32 parts.
