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.

When a mesh datablock is pinned in the properties panel,
`context.object` is `None`. This in turn causes `obj.mode` to raise an
`AttributeError` exception as `None.mode` doesn't exist.
Since there is no (fast/simple) way to check whether the owning object
is in edit mode or not, the properties will be disabled. Not ideal, but
better than spewing an exception on every panel draw.

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.
The issue was caused by un-initialized local storage for volume
intersection hits which are supposed to be stored in per-thread
KernelGlobals.
Fix is to make thread_shader() be the same as thread_render() in
respect of KernelGlobals.

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().
