Sat Aug 24 13:57:01 1996 Alexandre Julliard <julliard@lrc.epfl.ch>
* [controls/scroll.c]
Renamed SCROLLINFO to SCROLLBAR_INFO to avoid conflict with Win32.

New perl script to generate the wine.conf file.

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.

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.
