BMesh: avoid redundant face-exists check (dyntopo)

BMesh: optimize BM_face_exists

Avoid flagging/clearing flags,
just walk over the face until a mismatch is found.

Cleanup: warnings

Cleanup: don't use single sets for comparisons

Fix for *harmless* T44342 Error when saving multilayer EXR

This was introduced with multiview, and it was an oversight on my end.
There is no error, we simply was never returning True

Fix T44362 no easy way to repeatedly duplicate keyframes in action
editors.

Reporter used a hacky work-around by placing cursor at end of keyframe
range and doing ctrl-C ctrl-V repeatedly. This was working on 2.73 but
not anymore since the old selection is not kept.

Much better is to have duplication operator be repeatable. This commit
takes care of that.

cleanup: style

to match my earlier commit in temp_viewport_fx_merge branch

plus more

no functional changes

Cleanup: do not use _reportf() when not doing any string formating!

Also usual minor i18n messages stuff...

Moar precision for Color Stop position slider in Color Ramps

Normal dragging now uses a precision of 0.01 instead of 0.1, shift+dragging now uses 0.001. (0.1 steps can still be done using ctrl)

Requested by @venomgfx

Fix bug with autonormalization and transform (after own range commit).

Transforming the center after transforming a handle would continuously
flush an extra offset to the handles.

Also use normalization range of -1.0 to 1.0 instead of -0.5 to 0.5 (not
really important, just for better comparisons)

Fix for crash with non-camera as a camera

After user feedback:

* Allow ctrl click to do negative stroke in line strokes
* Use alt for angle constraints.

Revert "Fix hair random rotation limited to 180 degrees"

This reverts commit 176ed5bfe280ef2151f93c0940d54498aaf00d71.

Graph editor:

Normalization feature now uses the full range of the data instead of
just one semiaxis for the maximum size.

Fix T44359: `mesh_normals_loop_custom_set()` would not behave correctly with zero-normals.

Zero-normals here are used as a shortcut to say 'use auto-computed values'.
So we have to do so in pre-process steps!

Fix T44350: View3D layer out of sync /w scene

Workaround T44351: Scopes make editmesh lag

Scopes are very heavy to calculate and editmesh uv's can cause the image view to redraw.

Best just disable scopes in this case.

New operator for action and graph editor that centers around current
scene frame, bound to numberpad zero.

BMesh: resolve skinny face artifacts /w dyntopo

Dyntopo can currently create skinny faces,
especially when the faces are much larger then the resolution.

To get the old behavior, set debug value to 1234
