Fix #28301: Sculpting a object with rotational have desface

Browse Source 
Patch from Juha Maki-Kanto

- initgrabz was called with local space coord.
- Brush radiu was multiplying by 2.0 for grab and snake brushes.
  Not sure why this was needed. Made some tests and didn't notice
  any regressions without this multiplication.
