Fix #26218: texture paint

- Added option "Fixed Texture" to the UI. Because of strange reason,
  this feature was implemented but hidden from users.
  Would be cool, if somebody familiar with 2d texture paiting check.
- Fixed some issues in existing code of fixed texture paiting.
  It now handles brush radius and curve correct.
- Also fixed issue with paiting with texture from node tree - it used
  to be painted with regular brush color instead of texture.
