DC_GRADIENT and DC_BUTTONS

I noticed that, for some time it seems, a couple of flags for DrawCaption()
are missing.

DC_GRADIENT causes a gradient caption to be drawn (Win 98/2000 +), and
DC_BUTTONS causes the window title buttons to be drawn (XP +).

At the moment, I am running Windows 2000, so I am unable to verify if
DC_BUTTONS works or not. However, I guessed correctly for DC_GRADIENT (32),
and I'm pretty sure that DC_BUTTONS should be 64, since there aren't any
other documented flags than the ones listed.

I've also added DC_GRADIENT to the end of the DC_CAPTION style.

Changelog entry:

2003-08-19  Andrew Greenwood  <lists-JCKMKWeByS2j5a8ZAWZ3aFpr/1R2p/[email protected]>

        * include/winuser.h (DC_*): Add DC_GRADIENT and DC_BUTTONS
definitions, and add DC_GRADIENT to DC_CAPTION.
