- link to w32kdll instead of implementing all syscalls as stubs. I will remove the rest of the syscall code as soon as our syscall db is more complete - more TEST -> RTEST - update w32kdll_ros.def - add tests for NtGdiEngCreatePalette, NtGdiEnumFontOpen - Add some gdi handle table code to w32knapi - header cleanup svn path=/trunk/; revision=28619
