Fix for memory leak caused by re-making mipmaps

Problem was caused by different limits for "last" mipmap: it was 1x1
for mkaing mipmaps and 2x2 for re-making.

2x2 should be enough for mipmap.

Bug fix own collection:
- Recreate mipmaps if they're dirty when drawing background image
(this prevents "delayed" update of background image when you're paiting on it
in image editor).
- Mark mipmaps as dirty when inverting image channels.
