 Some environment variables can be set to alter how GEGL runs, this list might
 not be exhaustive but it should list the most useful ones.
 
+GEGL_QUALITY::
+    A value between 0.0 and 1.0 indicating a trade-off between quality and
+    speed. Defaults to 1.0 (max quality).
+BABL_ERROR::
+    The amount of error that babl tolerates, set it to for instance 0.1 to use
+    some conversions that trade some quality for speed.
+
+GEGL_CHUNK_SIZE:
+    The number of pixels processed simulatnously.
+
+GEGL_TILE_SIZE:
+    The tile size used internally by GEGL, defaults to 128x64
+GEGL_SWAP::
+    The directory where temporary swap files are written, if not specified GEGL
+    will not swap to disk. Be aware that swapping to disk is still experimental
+    and GEGL is currently not removing the per process swap files.
+GEGL_CACHE_SIZE::
+    The size of the tile cache used by GeglBuffer specified in megabytes.
+
+GEGL_DEBUG::
+    set it to "all" to enable all debugging, more specific domains for
+    debugging information are also available.
 BABL_STATS::
     When set babl will write a html file (/tmp/babl-stats.html) containing a
     matrix of used conversions, as well as all existing conversions and which
     optimized paths are followed.
-BABL_ERROR::
-    The amount of error that babl tolerates, set it to for instance 0.1 to use

 GEGL_DEBUG_BUFS::
     Display tile/buffer leakage statistics.
 GEGL_DEBUG_RECTS::
     Show the results of have/need rect negotiations.
 GEGL_DEBUG_TIME::
     Print a performance instrumentation breakdown of GEGL and it's operations.
-GEGL_SWAP::
-    The directory where temporary swap files are written, if not specified GEGL
-    will not swap to disk. Be aware that swapping to disk is still experimental
-    and GEGL is currently not removing the per process swap files.
