Cleanup: variable name

Cleanup: preprocessor indentation

Transform: default shrink/fatten even-offset to false

Changed for 2.8 but this cases spikes for some geometry, see: T59968

Fix new material for pinned objects

Grease pencil check was using active object.

Merge branch 'blender2.7'

Fix T60014: material link pref ignored

The PreferencesEdit.material_link only worked for adding slots,
adding an initial new material didn't respect the preference.

Fix T58859: render with compositor does not render other scenes.

Fix wrong alpha blending for datablock preview icons.

Fix (unreported): unpredictable crashes when it is done snap after automerge.

The `em->tottri` of an evaluated object can be different from the actual amount of looptris.

Merge branch 'blender2.7'

Fix T60061: Cycles OSL point density not working.

Add override keywords so we can detect when the function definitions change.

Fix T60037: single column layout breaks file browse button.

Fix T59063: operator search menu loses background in some cases.

Fix wrong grease pencil shader FX usage of object location.

It should use the evaluated object location, and not add any unnecessary
dependency on geometry data.

Fix T59792: Cycles crash rendering motion pass with motion blur enabled.

Fix T60051: Wrong stroke projection when viewmode set to Front

As the z-depth is calculated using the internal drawing, if we use the front mode the z-depth is wrong. The Front or Back mode must be used only for display, but not for calculation.

Fix T60046: crash with Cycles viewport render and particle info node.

This code was not correctly ported to 2.8.

Fix T60031: Joining two Grease Pencilobjects sometimes crashes

The drawing cache was not set as dirty and drawing engine used old data.

Fixes and edits to studio light operators

- Remove pathlib use
(was converting to/from string with no real advantage).
- Use user_resource(..., create=True) to ensure the path exists.
- Pass full path to BKE_studiolight_create, don't add extension after.
- Fix 'sl' filtering glob and move from ui code to operator.
- Fix string copy length.

Cleanup: py-gpu error checks

Move gpu initialization checks to the start of each function instead
of mixing with argument parsing.
