99fb654ffd DRW: Cleanup / Renaming of mesh batch cache functions
THis is in order to avoid the jungle of names being different at each
step of the API.

Also removes some unused functions.

36cc42e796 Mesh Batch Cache: Optimization & Refactor shaded surface support
This now only upload data per loops to the GPU, making use of index buffer
to draw polygon. This make use of the vertex cache, speed up renders
and saves a lot of vram.

Update performance is also slightly faster and can even be improved further
by updating only uvs or vcol independently.

This commits breaks texture paint batches. It will be added back in another
commit.

f371e633f9 Curve Batch Cache: Add support for loose edges and curve/surf modifier
Fixes T58298 Nurbs circle and curve dont draw in objectmode

18d0566013 Curve Batch Cache: Add back support for shaded geometry
This changes a bit the batches data structure. Instead of using one
vbo per material we use one for all material and use index buffers for
selecting the correct triangles.

This is less optimized than before but has potential to become more
optimized by merging the wireframe data vbo into the shading one.

Also the index buffers are not strictly necessary and could be just
ranges inside the buffer. But this needs more adding things inside
GPUIndexBuf.

2afed99da3 Curve Batch Cache: Rework Implementation to use new batch request
Shaded triangles are not yet implemented (request from gpumaterials).

This also changes the mechanism to draw curve normals to make it not
dependant on normal size display. This way different viewport can
reuse the same batch.

1d92888ee8 DRW: Batch Cache: Add batch request system
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()).

0c6d5232a3 DRW: Remove the use of GPUTexture buffers for edit wire rendering
See previous commit for detail as why.

e929cad706 DRW: Rework wireframe overlay implementation
The shader is way simpler and run way faster on lower end hardware
(2x faster on intel HD5000) but did not notice any improvement on AMD Vega.

This also adds a few changes to the way the wireframes are drawn:
- the slider is more linearly progressive.
- optimize display shows all wires and progressively decrease "inner" wires
  intensity. This is subject to change in the future.
- text/surface/metaballs support is pretty rough. More work needs to be done.

This remove the optimization introduced in f1975a4639.
This also removes the GPU side "sharpness" calculation which means that
animated meshes with wireframe display will update slower.
The CPU sharpness calculation has still room for optimization. Also
it is not excluded that GPU calculation can be added back as a
separate preprocessing pass (saving the computation result [compute or
feedback]).

The goal here was to have more speed for static objects and remove
the dependency of having buffer textures with triangle count. This is
preparation work for multithreading the whole DRW manager.

f1975a4639 Wireframe: Optimization: Only draw triangles that have edges
This only happens after a certain threshold.

We sort triangles into 2 bins (start and end of the buffer) based on a
threshold and just draw the start bin if the wireframe slider is low enough.

This optimization is disabled for deformed meshes.

This should help resolve (to some extent) T58188.

32ab0647a5 DRW: Implement Hair Weight drawing
Fixes T57931 Particle weight edit mode is not supported.

There is a bug that prevent refresh of the toolsettings on which is based
the weight / non-weight display selection (see T58086).

7d32d87a86 Viewport: implement hiding faces in paint modes.
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.

03d0219d7a Edit Mesh: Refactor edit mesh drawing
This decouple the vertex display from the face+edges.

This is to reduce the number of triangles required to fix the edges
artifacts (aliasing) and increase viewport reactivity when not actively
navigating (ie. mouse scroll).

Also it makes all vertices visible (not cut-off) even when navigating.

However it makes the navigation drawing a bit slower because it has to
render twice.

Also add a depth bias to the wires to avoid depth fighting when previewing
final mesh (modifiers applied).

283f0ae9af Edit UVs: Refactor drawing Shadow UV in Image Editor
Currently it's not showing the subdivided mesh (if there is a subdiv mod)
and there is some sync issue if there is multiple uv image space opened.
But thoses will be tackled later on. The purpose of this commit is to fix
the overflow issue of IMM and speed issue.

781995a09c Edit UVs: Refactor drawing Edit UV in Image Editor
NOTE: This commit only concern edit UVs and not the "shadow" mesh displayed
when texture painting. This will be address in a future commit.

We now cache the uv mesh in the mesh batch cache and only reupload data on
changes.

Update could be more granular (and a bit faster) but it's not our main
concern ATM.

This should fix problem caused by the IMM api used to draw large meshes.
This makes performance skyrocket compared to previous implementation.
There is still a big CPU bottleneck when not in sync selection mode but it
is not related to the drawing function directly.

af998b40a0 Implement correct drawing of advanced Weight display features.
This adds existing behavior from calc_weightpaint_vert_array
that was missing from the new rendering code:

- No selected Vertex Group displays as a solid pink color.
- Zero weight displays as alert color depending on Options.
- Multipaint mode correctly displays collective weight.

In order to properly implement this variety, a data structure
holding all relevant parameters is introduced.

a67cc72232 MetaBall support for Workbench + EEVEE
Note: Metaballs only support the first material slot. Splicing it per
material would create empty Batches. In order to overcome this we set
the batch for other materials to NULL. We added extra checks in EEVEE
and Workbench to not draw when the geom is NULL.

f9ca750bdf Wireframe: Change / Optimize the limited wireframe visibility option.
This make the limited wireframe not a performance problem anymore.

However, this does change the number of edges displayed as the threshold
is now computed per vertex instead of per edges.

For this reason we extended (internaly) the range of the slider so that the
users can hide more edge.

712885c30e DRW: Add wireframe buffer texture generation for wireframe drawing.
Only OB_MESH is supported for now.

Creates a simple index buffer with negative indices if the edges is not a
real edge.

Also create the buffer texture representation of this buffer along with the
pos_in_order buffer texture.

687f09a8ad Workbench: Optimize Shadows.
This makes the shadows ~10 times faster in the general case.

This only create extrusion geometry on the outline edges. Also we increment
or decrement the stencil buffer by 2 for each manifold edge and only by 1
for non manifold. This make the algorithm robust yet less heavy than creating
one prism for each triangles.

aefd181b0b Fix crash going to edit mode of particles with copy on write
We can not rely on edit->psys, it is not set for particle edit,
and there is some logic deeper inside which does different things
dependent on that.

We need to replace those checks with some some HAIR vs. PARTICLES
flag and always set psys pointer.

d50821f145 Particle edit: Initial support of edit with copy-on-write
The idea is that edit mode structure is owned by original object,
and used for drawing. This is a bit confusing, especially since
path cache is also in that structure and needs evaluated object
to calculate cache.

In the future we should split edit data from visualization data,
but that's bigger refactor.

a2b05accea Eevee: Fix vertex color being in srgb space.
Now they are properly converted to Linear space before interpolation.

Since the only way to get vertex color in eevee and cycles is via the
attribute node with the CD_AUTO_FROM_NAME flag, we have to know at binding
time which type of buffer will be connected to this auto input.

We store this information inside the batch cache (together with the according
uniform name) and pass it as uniform to the shader which does conversion if
needed. The same shader can then be reused to draw another mesh with
different auto layers configuration.

95b9680597 Draw manager: Make particle code drawing closer to old viewport
The way how particle state is to be accessed or used did not change
in Blender 2.8, so the drawing code should follow old design.

This code is somewhat duplicated from drawobject.c, but old draw
code is on the way to be removed anyway.

This fixes issue with disappearing particles when tweaking number
of particles.
