-Gallium Post-processing
-=======================
-
-The Gallium drivers support user-defined image post-processing. At the
-end of drawing a frame a post-processing filter can be applied to the
-rendered image. Example filters include morphological antialiasing and
-cell shading.
-
-The filters can be toggled per-app via driconf, or per-session via the
-corresponding environment variables.
-
-Multiple filters can be used together.
-
-PP environment variables
-------------------------
-
--  PP_DEBUG - If defined debug information will be printed to stderr.
-
-Current filters
----------------
-
--  pp_nored, pp_nogreen, pp_noblue - set to 1 to remove the
-   corresponding color channel. These are basic filters for easy testing
-   of the PP queue.
--  pp_jimenezmlaa, pp_jimenezmlaa_color - `Jimenez's
-   MLAA <https://www.iryoku.com/mlaa/>`__ is a morphological
-   antialiasing filter. The two versions use depth and color data,
-   respectively. Which works better depends on the app - depth will not
-   blur text, but it will miss transparent textures for example. Set to
-   a number from 2 to 32, roughly corresponding to quality. Numbers
-   higher than 8 see minimizing gains.
--  pp_celshade - set to 1 to enable cell shading (a more complex color
-   filter).
