We are still ditching the specular intensity of SSR (ssr_data.xyz).
But at least now there is some comment about it.
See T61704 for user reports on that matter.
Comments with the blessing of Clément Foucault.
If all axis and grid options were turned off, the grid in the main ortho views would not be rendered.
Now we force rendering of the grid regardless of the settings when in one of the main ortho views.

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.

The dependency graph now handles updating image users to point to the current
frame, and tags images to be refreshed on the GPU. The image editor user is
still updated outside of the dependency graph.
We still do not support multiple image users using a different current frame
in the same image, same as 2.7. This may require adding a GPU image texture
cache to keep memory usage under control. Things like rendering an animation
while the viewport stays fixed at the current frame works though.
This introduce the wireframe batches. Creating the indices buffer does
not seems to slow down the sculpt in my testing (but it is kind of hard to
test reliably)
This includes a bit of cleanup in gpu_buffers.c.
By default wire would z-fight against the surface.
Increase the bias, also don't adjust the 'w' component
since it causes bias that depends on the view direction.
Tested on an `AMD Radeon HD 7570M`.
It seems that a VBO containing only `unsigned bytes` or `unsigned shorts` can't be read correctly in a shader.
Strange that if the index buffer repeats the drawing of the vertices (as was done before rBa04dd15193e6) the problem disappears.
The disadvantage of this solution is that the memory size for a selection VBO increases by about 4 times.
But the loss in optimization is negligible.
Thanks to @fclem for pointing out the possible source of the problem and reviewing the fix.
This avoid edges covering a part of vertices.
This comes at a (very minor) perf cost as vertices can cover some edges
pixels and early discard them with the depth test. But this only happens
in artificialy dense mesh and is not a real problem for common cases.
This make sure only one line is drawn per edge.
It makes the function mesh_create_edit_loops_points_lines() non-thread safe
but this is fine as of now because nothing is multithreaded at this point.
Also this is the only function use this flag so it might be OK.
The side effect is that we don't need to use depth test in edit mode
overlay so the masking artifact will not appear.
This make it (theoriticaly) compatible with all supported hardware with
consistent results.
Also we now draw the lines with analytic anti-aliasing instead of relying
on MSAA (which offers less benefits in our case).
The remaining aliasing comes from edges cut in half by the mesh which is
not rendered with MSAA. Hopefully this is not too much distracting and only
happen if the face is almost parallel to the view.
