This is a step to finish the D4325 and fix the T61286.
Currently the grid is highlighted in steps of 10 out of 10, which is wrong for the imperial units as seen in `buImperialLenDef`.
The idea of the code is to pass the steps of the grid already dimensioned as a uniform.
Another important thing to note is that subdivisions now only affect the grid without unity.
This matches the 2.7x Blender versions.
No performance loss (almost no gain too).

For clarity sake, the batch cache now uses exclusively per Loop attributes.
While this is a bit of a waste of VRAM (for the few case where per vert
attribs are enough) it reduces the complexity and amount of overall VBO
to update in general situations.
This patch also makes the VertexBuffers filling multithreaded. This make
the update of dense meshes a bit faster. The main bottleneck is the
IndexBuffers update which cannot be multithreaded efficiently (have to
increment a counter and/or do a final sorting pass).
We introduce the concept of "extract" functions/step.
All extract functions are executed in one thread each and if possible,
using multiple thread for looping over all elements.

When using Vertex or Weight paint mode on a wireframe the overlay was
blended with the background. In this case we now use alpha blending.

The matrices that projects background images in the 3d view
were incorrect. The root cause was that the coordinate systems were not
respected, that was most noticeable when rotating a stretched image.
We re-validated conversions of coordinate spaces (UV -> Image -> Camera -> Window)
and made sure that the rotation is done in image space.

When drawing the selection buffer the camera images were drawn. This
resulted in unneeded extra clicking for the user. This change will
ignore camera images during the selection.

When in texture paint mode and in solid mode the object that is being
texture painted will be rendered by the workbench engine with textures.
All other objects would render the same. For other cases the texture paint
draw engine will still draw the texture.
The texture mode draw engine now only drawn the masks. The opacity
sliders influences the texture mask.
This change has been implemented conserably. In the future we need to
look into making this better, like adding support that every object
can be colored differently. Currently when rendering in the workbench
we can have up to 3 different color types active (what the user selected,
the fallback in case no materials have been configured and this one,
forcing textures)

The edit mesh is culled by object. When the object is not visible on
screen, the edit mesh may still be visible. This change will not cull the
edit mesh anymore.

We fix by separating the drawing of wire xray objects.
These wire objects gets drawn before normal wires and set the stencil to
0x0 just like the solid counterparts. Also a prepass is done to "dig"
through non-xray solid.
Migrate old legacy code to the draw mamager/object mode. The old legacy
version did not work with wireframe. By migrating the code
to modern draw manager code we have mode control on the drawing process.
Still background images do not work with OIT, the cause seems to be that the transparent pixels are treated as background pixels.
Also There are some artifacts when working with Holdouts and DoF, this
is because the draw engines do not pass the correct alpha values.

The Pose Bone Selection used normal matric multiplication, but that
mismatched the Depth buffer from all draw engines. They used the
optimized matrices from common_view_lib.
This change will use the optimized version, so the depth buffer matches
and the render artifacts would be correct.
Please note that bone selection is not using shcfg and therefore render clipping is still off.

This changes behavior from 2.7x, where selection & cursor could be
occluded by other objects.
Doing this without z-fighting in 2.8x isn't so simple because drawing
the text geometry is separated from edit-selection.
Change behavior since this doesn't seem like an important difference.
Fixes assert drawing text edit mode.
This was due to a double offset of the wireframe. We also reduce
the wireframe offset. The look of the wireframe overlay changes
a little with on distant wires.
Now texture storage of images is defined by the alpha mode of the image. The
downside of this is that there can be artifacts near alpha edges where pixels
with zero alpha bleed in. It also adds more code complexity since image textures
are no longer all stored the same way.
This changes allows us to keep using sRGB texture formats, which have edge
darkening when stored with premultiplied alpha. Game engines seems to generally
do the same thing, and we want to be compatible with them.
Depth testing was off as it used the precomputed ModelView matrix. As
draw engines currently use a different approach the depth was sometimes
a bit off making the color disappear.
This change will use a different vertex shader that will write the
correct depth. I expected the same change to be needed in the bone
selection overlay but was not able to reproduce it.
