* pipi.c: reimplement pipi_new() without relying on the underlying codec
library, so we can have several or none of them at some time.
* sdl.c imlib.c: allow to save images that weren't created using the
current codec.

* Big API reorganisation. Now libpipi can transparently convert between
colour spaces for a given image. For instance, if pipi_gaussian_blur is
applied to a 32-bpp image, it is automatically converted to gamma-corrected
32-bit floats beforehands, then converted back to normal.
* TODO: clipping, regions of interest, more formats, getpixel macros...
