Hans de Goede 02ff0a5d7e xf86RandR12: Fix XF86VidModeSetGamma triggering a BadImplementation error
Commit b4e46c0444 ("xfree86: Hook up colormaps and RandR 1.2 gamma code")
dropped the providing of a pScrn->ChangeGamma callback from the xf86RandR12
code. Leaving pScrn->ChangeGamma NULL in most cases.

This triggers the BadImplementation error in xf86ChangeGamma() :

    if (pScrn->ChangeGamma)
        return (*pScrn->ChangeGamma) (pScrn, gamma);

    return BadImplementation;

Which causes X-apps using XF86VidModeSetGamma to crash with a
X protocol error.

This commit fixes this by re-introducing the xf86RandR12ChangeGamma
helper removed by the commit and adjusting it to work with the new
combined palette / gamma code.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
