I had to change something that was annoying me and discovered another couple minor flaws.

Changelog

• Adjusted dither2a.bs.
  • Now, instead of having a Dither Density setting, you use the opacity slider to change the density.
    It’s a little less precise, but it means you don’t have to adjust the density when you change what dither pattern size you’re using.
  • Consequently, the Variable Max Density Setting has been removed, and the Invert/Halve Pattern settings have been un-merged.
  • Note: Due to these changes, I will probably no longer include dither.bs in future versions of this pack, as I feel it is completely obsoleted by dither2.bs and dither2a.bs.
    There is a possibility that dither2.bs may also stop being offered, but that’s something I’ll think about in the future.
• Adjusted behavior of Opacity/Density by Pressure settings on all relevant brushes.
  • It now always draws at least the minimum opacity/density possible.
    Before, it was possible for the pressure/opacity to be so low that the brush would draw nothing.
• Fixed Spacing setting on all relevant brushes.
  • Brushes drew too often when Spacing was set higher than 1, except for dither-old.bs, which drew too infrequently.
