without scale/rotation-based spacing

Krita uses only the brush offset to calculate the spacing.

This leads to a bad result in a number of cases. For example: at the end of the stroke when we no longer lead with the pen but only release it.

Or when we want to make a short stroke with increasing pressure (see attachments)

STEPS TO REPRODUCE
1. (see attachments)
2. take any smudge brush
3. draw a short stroke (or press without offset) with a large pressure difference at the beginning and end
