GPencil: Disable Smart Smooth when Random is enabled

These options cannot be used at the same time because the Smart Smooth is designed to remove any imperfection in the stroke and the random options are designed to create these imperfections, so the smooth removes all randomnes.

Cleanup: Fix comments

GPencil: Sculpt brushes uses affect position flag

This commit changes the following:

1) The affect parameters have been moved to brush. Before, this parameter was by toolsettings and this was wrong.
2) Intialize the affect postion to ON.
3) If affect position is OFF, don't apply Sculpt brush effect.

GPencil: Limit internally Smart Smooth to range 0 to 0.5

In the UI we keep a range between 0.0 to 1.0 for usability reasons, but internally, the value is divided by 2 to limit the real between 0.0 and to 0.5 and also makes it less sensible.

GPencil: Remove Active Subdivide parameter from Brush

This parameter is not required with the last changes in paint smooth.

GPencil: Use original strokes, not evaluated

USD: removed the temporary code for timing code execution

USD: stricter viewport locking when exporting

This is to prevent crashes like we had with the Alembic exporter (T65816).

Cleanup: added my name to TODO comments

Cleanup: remove scene parameter from USD_export()

The Context is passed to USD_export() anyway, which already contains the
scene.
