Add 'runall' target.
...
The ‘runall’ target runs the rotation on different sizes:
- 512x512
- 1024x1024
- 3000x3000

Add support for PGM format.
...
The code has been split into different source files.
This breaks for now rotation for tiled images and PPM format. The focus
is now on the PGM format.

Remove RGBX structure.
...
The pixels are still packed as RGBX in memory but
no structure is created, it’s just a contiguous buffer.
Interpolation is now done with SIMD on integer values.
- Add SIMD define.

Create small overlap in tiles.
...
Tiles overlap on the bottom line and the right column.
Having an overlap allows us to get neighbor points for each point in a
tile, regardless of its position.

Fill a temp buffer for each line.
...
We don’t write into the memory right away, we first write to a temp
buffer that we blit into the rotated image.
