-     * - pMarkPicture may have componentAlpha set, which greatly changes
-     *   the behavior of the Composite operation.  componentAlpha has no effect
-     *   when set on pSrcPicture or pDstPicture.
-     * - The source and mask Pictures may have a transformation set
-     *   (Picture->transform != NULL), which means that the source coordinates
-     *   should be transformed by that transformation, resulting in scaling,

-     *   coordinates for you.  Transforms have no effect on Pictures when used
-     *   as a destination.
-     * - The source and mask pictures may have a filter set.  PictFilterNearest
-     *   and PictFilterBilinear are defined in the Render protocol, but others
-     *   may be encountered, and must be handled correctly (usually by
-     *   PrepareComposite failing, and falling back to software).  Filters have
-     *   no effect on Pictures when used as a destination.
-     * - The source and mask Pictures may have repeating set, which must be
-     *   respected.  Many chipsets will be unable to support repeating on
-     *   pixmaps that have a width or height that is not a power of two.
-     *
-     * If your hardware can't support source pictures (textures) with
-     * non-power-of-two pitches, you should set #EXA_OFFSCREEN_ALIGN_POT.

-     * private record, for sending to the hardware with each drawing command.

+     *   when set on pSrcPicture or pDstPicture.

+     *   coordinates for you.  Transforms have no effect on Pictures when used

+     *   as a destination.

+     * - The source and mask pictures may have a filter set.  PictFilterNearest

+     *   and PictFilterBilinear are defined in the Render protocol, but others

+     *   may be encountered, and must be handled correctly (usually by

+     *   PrepareComposite failing, and falling back to software).  Filters have

+     *   no effect on Pictures when used as a destination.

+     * - The source and mask Pictures may have repeating set, which must be
