* pixels.c: clamp pixels in the float32 -> rgba32 conversion to avoid
artifacts.

* 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...

* pixels.c: do not return a white pixel when calling getpixel() outside
the image boundaries; instead, return the closest pixel in the image.

* Import image loading features from PWNtcha. As they are more than 4-year
old, they will certainly require some cleanup, eg. pkg-config transitions.
