Grease Pencil Advanced Picker

/!\ FOR BLENDER 2.93 /!\

A Grease Pencil Picker to retrieve and set the Layer and Material by sampling a stroke. It will save time searching for them and will solve those "Damned, wrong layer!".

The add-on adds a Picker on the ToolBar of the Grease Pencil Draw mode. To use it, simply clic on a stroke you want to sample, it will set the current active Layer and Material from the stroke that has been sampled.

"Alt + Q" can be used as a shorcut.

I've included the .blend file used in the demo as well.

Version 1.1 :

- Fix wrong sampling when there's a custom transform on the object.

- Add "Eyedropper" icon.

- Now sample the position of a stroke by placing the 3D Cursor on the origin of that stroke : it allows to be sure to be at the right depth while drawing.
