When using opengl attributes such as gl_VertexID in a shader its
location is set to -1. This location was used without checking in an
attribute array. This fails big time when called from python. For
example `print(shader.format_calc())` made python crash immediately.

There was an workaround implemented for specific the Intel HD Graphics
4000 GPU on Windows platform. Other GPU from the same series also need
this workaround.
We will enable the workaround for specific drivers.

The issue was the the copy data function didn't copy the active canvas number.
So it would always be 0 and thus use the first canvas when trying to bake.
Also fix not copying unused type data (unused canvas/brush settings).

When the slot of the material is empty, the loop to lock the materials tried to use the material but this was NULL.
Check if material is NULL before using it in other operators too.
We need to indicate a preferred size to avoid `RGN_FLAG_TOO_SMALL` the first time the region is created.

Although the Auto-Run Python Scripts flag isn't used,
this is still a security risk since exclude paths list is.
Further this isn't what users would expect when loading a file &
only some preferences were being loaded so it's not useful.
It should be based on the mesh bounds before modifier stack evaluation, but
some modifiers were causing it to be recomputed. The flag to disable texture
space recomputation was not preserved through modifier evaluation.

Seems the deform group index and deform vertices went out of sync somehow.
Added extra NULL pointer check, which seems to be safe and matches checks
in other places in the neighbourhood.
When `BKE_mesh_new_from_object()` cannot convert an object to a mesh, it
returns `NULL`. This case was not handled at all in
`BKE_mesh_new_from_object_to_bmain()` or `curvetomesh()`, causing a
segmentation fault.
This commit fixes the segmentation fault, and leaves the curve object as
a curve object.

Note: Although this fixes the issue (as in, it prevents a crash)
BKE_reports are not working because of CTX_wm_window_set().

A mouse click in the window will trigger the `VIEW3D_OT_cursor3d` operator
before the viewport is available. This causes a segfault in
`GPU_viewport_engines_data_validate()`.
Other callers of `WM_draw_region_get_viewport()` already check for `NULL`
being returned and handle it gracefully.

Init the scene of the draw context when selecting. When using face dot selection on
when the subsurf modifier is active on the cage, the scene needs to be
valid. It is read from the context in the
`DRW_mesh_batch_cache_create_requested` and used in the `isDisabled`
method of the SubSurfModifier.

Restore some context overrides which were originally happening in 2.79.
Made it a bit more paranoid, by storing old values and restoring them
afterwards, so the context is not being changed at the end of the function.
When the object we iterate over is not part of the depsgraph, we cannot
get the evaluated copy to export. This workaround is temporary to avoid
a BLI_assert() failure getting the evaluated mesh of this object.
This will be handled more elegantly in the new AbstractHierarchyIterator
that I'm working on, but that requires a bigger change than we should
allow this close to the 2.80 release candidate.
This fixes a problem described in T58686.
