xorg-x11-drv-mga bug fix and enhancement update

Updated xorg-x11-drv-mga packages that fix several bugs and add one enhancement
are now available for Red Hat Enterprise Linux 6.

The xorg-x11-drv-mga packages porvide a video driver for Matrox G-series
chipsets for the X.Org implementation of the X Window System.

The xorg-x11-drv-mga packages have been upgraded to upstream version 1.4.13,
which provides a number of bug fixes over the previous version. (BZ#713858)

This update fixes the following bugs:

* Previously, the MGA driver rendered the image incorrectly on big-endian
architectures, including PowerPC and 64-bit PowerPC. Consequently, the display
showed altered colors. With this update, the colors are displayed correctly in
the described scenario. (BZ#713388)

* Previously, the MGA driver caused a shift in the video screen. Consequently,
the screen became corrupted and the windows were pushed around randomly. This
update, modifies the code so that the MGA driver no longer causes problems for
the video screen. (BZ#745080)

This update also adds the following enhancement:

* This update adds support for ServerEngines Pilot III to the xorg-x11-drv-mga
packages. (BZ#526104)

All users of the Xorg x11 MGA driver, are advised to upgrade to these updated
packages, which fix these bugs and add this enhancement.

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.
