* gdk/win32/gdkgc-win32.c (_gdk_win32_gc_new): Use the same
default values for fg and bg pixel as X11 does (0 and 1), not
black and white. Use PS_ENDCAP_FLAT and PS_JOIN_MITER by default.
Use 0 for pen width by default (treated as 1 anyway later, but for
apps that might check the value in the GdkGC).
(gdk_win32_hdc_get, gdk_win32_hdc_release): New functions, public
interface to gdk_gc_predraw and _postdraw.
