Cleanup: style

Fix compiler error in Windows

Merge branch 'master' into blender2.8

Cleanup: use const for BKE_object args

Merge branch 'master' into blender2.8

Logging: replace 'fwrite' w/ 'write'

We're already buffing output, so use write directly.

Cleanup: rename WriteData struct members.

Relationship between tot/count/buf wasn't clear.

Also use doxy sections.

Undo: refactor memfile writing

- Move static undo variable into 'WriteData',
'memfile_chunk_add' used arguments in a confusing way,
sometimes to set/clear static var.

- Replace checks for 'wd->current' with 'wd->use_memfile'
move memfile vars into 'wd->mem' struct.

Fix T54568: Undo memory de-duplication failed

Error in 651b8fb14e caused de-duplication to fail.

BGL: Expose OpenGL API for FrameBuffers and RenderBuffers.

Merge branch 'blender2.8' into blender2.8-workbench

Workbench: Silhouette shading

Currently it uses the `obj->col`. This needs to be made more intelligent
with fe collection overrides.

PyAPI: Gawain: Checks the member `data` instead `vbo_id`.

After recent changes in gawain, `vbo_id` is now assigned in VertBuf creation.

RNA: Fix crash with select_mode_update.

`bpy.context.tool_settings.mesh_select_mode = (True, True, True)` was crashing because `wmn->window` was not being passed.

DRW: Deferred Shader Compilation: Optimize shaders compilation.

`glFinish()` that was causing bad perf issue on `Intel(R) HD Graphics 4000`.

CLAY: Fix prepass shader on certain compiler.

`Intel(R) HD Graphics 4000` driver sometimes does stupid things.

Python API: remove preview/render resolution settings from API functions.

For correct results these must have been set already when the depsgraph was
created and evaluated, so all dependencies have appropriate resolutions too.

For particle we no longer backup and restore the viewport particles to avoid
overwriting them during render, as copy-on-write solves this for us. Even
without COW particles seem to work ok.

This also removes the particle simplification options based on camera. This
was never used much and only available in Blender Internal.

Depsgraph: don't pass evaluation context to update functions.

The depsgraph now contains all the state needed to evaluate it.

Depsgraph: remove engine type from evaluation context.

This was only used for viewport rendering, where we can just pass the engine
type directly. There is no technical reason why we can't draw the same depsgrpah
with different render engines.

It also led to some weird things like requiring a render engine for snapping
and raycast API functions.
