RLE compression is now working fully on save. File sizes are now competitive with Photoshop's.
- Saving takes about twice as long with RLE compression as for uncompressed files.
- To compensate, loading and saving have been parallelized at a coarse granularity. This also speeds up operations in general.
Further performance improvements, independent of the parallelization:
- Reduction in memory consumption when saving.
- CMYK files now load twice as fast.
- Lab files now load 3x as fast.
