	Added a lot of functions to the DC func table.

	* [loader/pe_image.c]
	Initialise %fs before calling out to 32-bit code.

	* [windows/hook.c]

Tue Aug 20 21:00:00 1996 Alex Korobka  <alex@pharm.sunysb.edu>

	* [controls/menu.c]
	Adjust popup menu coordinates so that it always stays within

Mon Aug 19 13:33:13 1996  Stephen Simmons  <ssimmons@vitsemi.com>

	* [tools/wineconf]
	New perl script to generate the wine.conf file.

Fri Aug 16 15:31:44 1996   John Harvey <john@division.co.uk>

	* [if1632/gdi.spec]
        Lots of printer functions.
	
	* [include/callback.h]
        New functions for printer driver support.

	* [include/gdi.h]
        New/changed structures to support printer driver.

	* [misc/escape.c]
        New version that uses function table in DC structure.

	* [objects/dc.c]
        CreateDC copes with things other than Display.
	X code for CreateDC moved to graphics/x11drv directory.
	CreateCompatibleDC copies func table from original DC.

	* [objects/font.c]
        GetTextExtentPoint32A,GetTextMetrics16 use function table in
        DC and code moved to drivers directory.

	* [misc/printdrv.c] [graphics/*/*] [include/win16drv.h]
        New files for printer support. 

Fri Aug 16 12:33:00 1996  Bruce Milner <Bruce.Milner@genetics.utah.edu>

	* [controls/scroll.c]
	Added SetScrollInfo32 and GetScrollInfo32.  These just call existing
	code. There are a few options in which I'm probably the wrong person
	for the job (page size and disable bar). There are comments in the
	code as to what they should do.

	* [objects/gdiobj.c] [objects/font.c] [include/font.h]
	Added 32 bit version of FONT_GetObject.
