some comments
transform-op: complete the renaming of affine to transform
gegl: set gegl-config default chunk-size to 512 * 512

otherwise make check fails for tests/compositions/clones.xml
gegl_buffer_set_pixel: fix inverted fish

soft_format is the real buffer format
Added Latvian translation
buffer: clean up public gegl-buffer-backend.h header
buffer: move Class typedefs back to their own headers
gegl: switch tile cache size handling to 64 bit

and add a new GeglConfig property "tile-cache-size" of type guint64,
"cache-size" still exists but is deprecated and will go away in
gegl-0.3.
gegl: restore GeglConfig's default 128x64 tile size
removing "OpenCL/" includes in cl headers for Apple (Bug 673969)

that's the point of having them in our code after all.
buffer: ref the added handlers in gegl_tile_handler_chain_add()

and unref them in the caller after adding it.
buffer: gegl_tile_void() comment to explain why pyramid invalidation is b0rk
buffer: formatting and other minor cleanup in GeglTileBackend
buffer: add private "cache" and "tile_storage" members to GeglTileHandler

and private API to set/get them. Also add to-become-public API to create
and dup tiles. In gegl_tile_handler_chain_add(), set the chain's own
storage and cache on the added handlers. Set them on the chain itself
in GeglTileStorage (which is a chain). Port the cache, zoom and empty
tile handlers to use the new stuff.
buffer: install gegl-tile-backend.h, included via gegl-buffer-backend.h
