* 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...

* Test implementation of Gaussian blurring. It's awfully slow and does not
use the separation property, but it's just for a test.
