The only difference from 2.7x is that we were using glLineWidth(2.0) before,
which is not supported reliably in the latest OpenGL.
Big thanks to Clément Foucault for helping with this, on the design as well as
debugging the implementation.
For the records, I'm creating and destroying batches for the path geometry at
every draw. The pipeline is as follows:
1. Create GPUBatch with all the points
2. Create new shgroup with simple shader
3. Add call with the gpubatch
4. Save it in a linked list in stl->g_data
5. Free it after all drawing is done
* Draw bundle names.
* Draw bundle shapes (but spheres).
* Draw custom colors for bundles.
* Support selecting bundles.
* Object bundles also fully tested.
Missing from this commit:
* Camera path.
* Spheres are not drawn as solid.
* Blue dashed line from camera to tracker objects.
Note to myself, next time, better check the fix before pushing it.
GL_ARB_texture_gather is defined if there is support for the extension
not only when the extension is enabled. Do this check ourself with
GPU_ARB_texture_gather define.
Original fix 822de6e9e1
The extension GL_ARB_texture_gather is reported to be supported and does
not trigger an error when enabled but the textureGater functions are not
defined.
Workaround is to disable the use of this extension on such systems.
This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.

This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
This does not fix the smokesim. It only port the drawing method.
The Object mode engine is in charge of rendering the velocity debugging.
Things left to do:
- Flame rendering.
- Color Ramp coloring of volume data.
- View facing slicing (for now it's only doing sampling starting from the
volume bounds which gives a squarish look)
- Add option to enable dithering (currently on by default.
Trying to have a single option for this is too likely to be
insufficient in some cases.
Instead, support object type visibility & selectability per view-port.
This patch will allow users to customize what object types will be drawn by the object mode overlay.
It supports: Empties, Lamps, Cameras, Speakers, Armatures and Lightprobes.
It currently does not support Physics objects due to the overlap it has with other objects types.
Also be aware that in pose mode the armature is drawn, but not by the object mode overlay

Added a option to the overlay popover that controls the visibility of
non-renderable objects like lamps, cameras, speakers, armatures, curves
empties and force fields.
After discussion we went for a single option with more detailed check in
the object_mode draw engine.

This reverts commit 9129319647.
This meant users needed to select everything to see relationship lines,
this isn't always easy since objects can have limit-selection set.
This could be made into an enum option if it's important.
This method is a bit more optimized than the very first one
because it does not rely on the adjacent faces properties.
That said it's still a bit slower than the per vertex method.
