2D image sampling with filtering functions.
All functions take (u, v) texture coordinate, non-normalized (i.e. ranging from (0,0) to (width,height) over the image).
Any filtering done on texel values just blends them without color space or gamma conversions.
For sampling float images, there are "fully generic" functions that take arbitrary image channel counts, and arbitrary texture coordinate wrapping modes. However if you do not need full flexibility, use less generic functions, they will be faster (e.g. #interpolate_nearest_border_fl is faster than #interpolate_nearest_wrapmode_fl).

TODO(sergey): Consider making this function inlined, so the pixel read callback could also be inlined in order to avoid per-pixel function calls.
