[-] Quaternions
[X] Draw rotated pixels in src order
[X] Use atan2 at beginning and end of line.
    Interpolation in-between values
[X] Test pixel perfect 90
[ ] Fix out-of-bounds pixel set

[ ] Optimization for square images?
[ ] Fixed point computation?

# Cache
[X] Rotate per channel -> no gain
[ ] Load pixels in uint64-t
[ ] Cut image in tiles

# Quality
[X] Interpolate using SIMD, SSE (no big gain)
Add check_90(). - Fix border. 2014-06-26 21:28:34 +02:00			`[-] Quaternions`

FIll new interpolated pixels. - Take input image in argument. - Allow set_pixel() out of bounds, noop. 2014-06-26 23:45:02 +02:00			`[ ] Fix out-of-bounds pixel set`

Use a unique buffer for pixels (scanline). - Add rotate_pixel(). - Remove APoint, use Point instead. 2014-06-28 13:52:24 +02:00			`[ ] Fixed point computation?`
