This makes it possible for engines to ask for batches and only fill their
data after all engine populate functions have run.
This means that, when creating the batches data we already know all the
batches that are needed for this redraw and the needed data.
This allows for less redundant data preparation and better attrib masking.
Ideally, we should run all viewports populate function before executing
the batch construction but this is not the scope of this patch.
Conversion from the old request method will be progressive and both can
coexist (see uses of mesh_create_pos_and_nor()).
This only happens after a certain wireframe threshold.
We sort triangles into 2 bins (start and end of the buffer) based on a
threshold and just draw the first bin if the wireframe slider is low enough.
This optimization is disabled for deformed meshes when playback is active.
This optimization is only implemented for meshes object for now.
This should help resolve (to some extent) T58188.
The cause is that FOREACH_OBJECT_IN_MODE_BEGIN assumed that the active
object is in the correct mode, which is wrong in this case. It also
only considered objects of the same type as active, which had to be
replaced with an explicit type parameter.
In 2.79 hiding works in paint modes with selection enabled,
so it is a missing feature. This implements it in texture
paint overlays and in workbench base shading.

Bring back per-viewport localview. This is based on Blender 2.79.
We have a limit of 16 different local view viewports.
We are using both the numpad /, as well as the regular /.
Missing features:
* Hack to make sure lights are always visible.
* Make rendered mode with external engines to support this as well
(probably just need to support this in the RNA iterators).
* Support over 16 viewports by taking existing viewports out of local view.
The code can use a cleanup pass in the future to unify the test to see
if an object is visible (or we can use TESTBASE in more places).
Now it shows more compact info below the view/object name. Render time and
memory usage is left out, as in most cases this is not so important. These
could be added back optionally if needed.
Move the weight paint drawing to the fragment shader. The shader
uses a texture that uses the U.coba_weight custom color band, or
an internal color band.
In addition to actual weights, the shader has to display two
alert colors: missing vertex group, and zero weight. The zero
weight alert has to be blended with regular weight colors,
so that a single alert vertex surrounded by weighted ones is
still visible.

We now treat Xray as being the mode where Limit selection to visible is off.
If Xray is OFF, Limit selection to visible is considered ON.
To allow 'see through wires' with solid shading (not Xray shading) we still
draw solid shading if Xray is ON with Xray Alpha set to 1.0.
This is using the existing engine (workbench forward) with 0.0 xray_alpha
and forcing wireframes on all objects.
There is no workflow/shortcut changes in this commit.
This make the workbench draw everything in the background routine just like
eevee. This is because the workbench uses floating point buffers too and
rendering background to this buffer makes it incorrect without proper
color management.
This could be improved because in xray the background is not blended but
dithered as it's drawn after the main pass.
instead of being ThreadLocal and leading to incorrect usage.
We still enforce no framebuffer when changing context. We can lift this
restriction later.
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 ignores the scene color managment view settings for solid mode and
lookdev when not using scene lights and world. The scene settings are
intended for tweaking renders and should not affect studio lighting and
matcaps.
There may be cases where a simple sRGB transform is better than Filmic
and we could add configuration for this. Not sure if it really matters
and it may be better if we just assume matcaps and studiolights are all
created for one view transform.
