  5. Warp : Add support for "bilinear" filter 

    This is a very low quality, but fast approach ( it also offer a way of profiling the performance of Sampler::sample( float, float ), which previously wasn't used anywhere critical )

    Might as well make it easy for people who want to do fast things with images?
