GSoC Editing Grease Pencil Strokes Using Curves

This patch includes all the changes made in the soc-2020-greasepencil-curve branch.

Major changes:

* Add a new "sub-mode" to grease pencil edit mode called "curve edit mode".
* Grease pencil stroke data structure has a pointer to a grease pencil curve. It will be saved with the stroke to the blend file.
* Most edit mode operators have been changed to work in curve edit mode.
* Transformation code has been adjusted to work for grease pencil curves.
* New source file added (gpencil_edit_curve.c) for operators exclusive to curve edit mode.

Cycles: added comments to light tree code

GPencil: Scale strokes to Potrace lib units

After doing a lot of testing, it looks the library is using a factor base on the VGA resolution and aspect ratio.

The formula was obtained experimenting and gets a very good result, but it could be a totally different approach if we find what logic is used by Potrace.

GPencil: Rename .h to .hh for C++ header files

This follows the new naming rules

GPencil: Avoid double geometry update when trace a stroke

As the sample function is already calling the update function, it's not needed to call again.

LineArt: Remove debug print.

Fixed a crash related to gridlines

Crash occured when transform of the fluid domain is changed.
Fixed by ensuring fluid before populating the cache.

LineArt: GPencil modifier flag change to mode (wrong use of variable).

Fix make outline color consistent
