Add pipi_release_pixels and pipi_set_colorspace in prevision of
pipi_get_pixels using the tiles system. These functions should
disappear one day, because they're going to leak like crazy.

Add a --gamma command to modify the global gamma value. This is a nasty
hack that will hopefully disappear in the future. The default gamma is
now 2.2 again (sRGB approximation).

* 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.
