Various fixes for gdi font handling code including: - Using TTs VDMX table to ensure that we get exactly that same size font that Windows uses. - Fixes to many members of the metrics structures. - Font cache. - Rotated text support. - Support for GGO_GRAY?_BITMAP (ready for anti-aliased text). - Support for GGO_NATIVE.
