Fix #25933: Drag Dog stroke method uses Jitter if set for other stroke method, but no jitter available.

Manually disable jitter usage for anchored and drag dot brush stroke metdhods.
Jitter slider is hidden in UI for this strokes so users can't set it to 0 by hand
and even if this slider would be visible in UI jitter gives wierd result for
this stroke methods.
