Objects that internally uses DispList do not cast shadow in the workbench.
Their outline is also not visible in object mode. The reason for this is
that edge detection was not implemented for Display Lists. This patch will
implement the edge detection.

When hiding the curve handles/points previously, the control points would still be drawn (loose verts).
Now we hide everything related to the handle if it is hidden.

This is work in progress. Look is not final.
This align data VBO data structure used for edti cage drawing to the one
use for normal drawing.
We no longer use barycentric coords to draw the lines an just rasterize
line primitives for edge drawing. This is a bit slower than using the
previous fast method but faster than the "correct" (edge artifact free)
method. This also make the code way simpler.
This also makes it possible to reuse possible and normal vbos used for
shading if the edit cage matches the
This also touches the UV batch code to share as much render data as
possible. The code also prepare for edit cage "modified" drawing cage (with
modifier applied) but is not enabled since selection and operators does not
work with modified cage yet.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

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.
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.
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.
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.
Now handles are drawn using index buffer instead of duplicating memory
requirement.
Also make use of shader tricks to draw handles antialiased, and respond to
UI scalling.
Make vertex point match edit mesh vertex size.
