My inking pack bundle.

SUMMARY
When using my inking pack, I noticed that the brushes that use speed are suddenly super-sensitive to speed, where previous Krita they were the opposite of super-sensitive. Overall, this is good. I am making this report so we can remind ourselves to write a warning message for 5.1, that people should update their brushes' speed sensor, much like we did for the flow-opacity changes.

STEPS TO REPRODUCE
1. Import my brush pack (attached).
2. Select "inking pen small new"
3. try drawing.

If you adjust the speed sensor on the size option to not end at 0, then it works a little bit more expected.

Testing with the Dec 28 5.1.0-prealpha (git 7f46859) on Debian 10:

For 'old' brushes, it should be possible to reduce the sensitivity in the Tablet settings by dragging the 'Maximum brush speed' to its maximum value. This does have a small effect.

I modified Basic_5 Size to have its size controlled by Speed with straight line transfer curve and set the 'Maximum brush speed' to 50 (mid range).

With a 2048 x 2048 canvas, I couldn't get it to go to maximum size.
With a 1024 x 1024 canvas, it very easily went to maximum size.

These results did not seem to be repeatable in a proportional way for different canvas sizes.
