[X] first tile on each row is missing
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`

Interpolate on quantized values for tiled images. 2014-07-08 08:04:43 +02:00			`[X] Fixed point computation?`
Use a unique buffer for pixels (scanline). - Add rotate_pixel(). - Remove APoint, use Point instead. 2014-06-28 13:52:24 +02:00

Fix first rotated tile on each row. The first tile on each row seemed to be missing values. This was due to the ‘continue’ statement that would prevent src_rotated_point to be incremented properly. 2014-07-04 00:34:06 +02:00			`[X] first tile on each row is missing`
