Merge remote-tracking branch 'origin/master' into blender2.8

--debug-gpu-shader: Dump GLSL shaders to disk

This is really convenient for development. Either for profiling the
generated shaders or to check if the generated code is correct.

It writes the shaders to the temporary blender session folder.

(ported over from blender2.8)

transform_snap_object: Do not use occlusion test when X-Ray is enabled.

Fix inaccuracy of SCREEN_OT_area_split when snap to midpoint and adjacent.

By default when moving a edge of the screen it always snaps to an invisible grid with unit of 4 pixels.
This was also affecting the snap to the midpoint and adjacent.
The solution was to make the snap to areagrid optional and use values of `origmin` and `origsize` that match the transformations in screen_edit.c.

Fix crash running in background mode

Cleanup: quiet warnings w/o Python

Fix crash if no tool is set

Merge branch 'master' into blender2.8

Cleanup: warning

Fix UI for camera data

The fix bit is the split.

But since we are using col.separator() left and right we need this as well.
I still don't think the separators are the way to go, yet may as well be
consistent with the current design in place, thus the extra separator here too.

UI: re-order navigate manipulator

Looked as if size applied to navigation too.

UI: use single column properties for object data

patch by @billreynish w/ minor edits

Merge branch 'master' into blender2.8

Cleanup: trailing whitespace (comment blocks)

Strip unindented comment blocks - mainly headers to avoid conflicts.

Cleanup: whitespace

Added ability to apply seams to all middle edges
between the 2 marked edges. currently does not make changes to material
or sharpness of edges

Modifiers: ported applying modifier from DerivedMesh ? Mesh

Boolean modifier: fixed crash when applying the modifier

X-Ray: Added a slider for the alpha

- will not render when set to 0.0 for speed reasons. so when user sets
transparency to hide everything the bigger passes will be skipped.
