Cleanup: style

Fix "Follow Active Quad" poll function

Since this uses the active face this only makes sense in edit-mode.

Fix T60172: UV smart project fails for unselected active object

Support multi-object edit-mode too.

Fix T62526: Can't scroll redo panel

Comments: correct ARegion.sizex/y comment

Also remove unused 'fsize'

Eevee: Fix black mesh when tangent is not present

In this case, the generic vertex attribute is {0,0,0,1}. So we look for
this case.

This fixes black text objects with a normal map applied. Also this could
help porting sculpt mode drawing to Eevee without supporting normal
mapping.

Note that will just fix black meshes due to T61870 but objects will not
show their normal map. So it's not a fix for this issue.

Fix T60170: Eevee: smoke color does not apply permanently

This was because color is not present in the density texture if there is
only one constant color. Adding it as a uniform.

Fix T59445: top bar hides everything when there isn't enough space.

Left and right aligned regions get hidden when there is not enough space,
and the main center region was empty. Now remove the left region and put
its contents in the center region, so that it always remains.

Merge branch 'blender2.7'

Fix T62156: Hair particle only shows up in final render when visible in viewport

Draw manager was checking for particles being enabled in viewport, but
actual evaluation was happening for render. Now the check in draw manager
properly follows current evaluation mode.

Additionally, de-duplicated some check, by moving everything needed to
a single place.

Annoying part is the const-cast, that could be cleaned up later by
modifying some underlying functions.

Build environment: require Alsa/OSS/PulseAudio backends for OpenAL on Linux.

Otherwise we can silently build an OpenAL that can't actually playback audio.

Fix T60434: crash with OSL and viewport + preview render at the same time.

Don't free LLVM JIT memory until process exit, there might be multiple OSL
instances using it.

Build environment: backport master changes to blender2.7.

We can keep these in sync for now.

GPencil: Cleanup code

Fix T62521: Fake dependency cycle with spline IK

The core was hooking up relation to a wrong operation, in an
attempt to cause proper full update of the pose (since there
is no intermediate state stored anywhere). This is now done
as a part of flush_handle_component_node(), so can properly
route more granular relation.

This fixes the crash which was caused by an access of partially
evaluated data by solving the fake cycle. However, if there
is a real cycle involved the code will still not survive, but
this is more generic issue (which also includes modifiers
for meshes and curves).

T62446: Mouse cursor disappears on Grease Pencil stroke

Before the cursor was only visible after the cursor moves over side areas, but not in viewport area.

Now, as soon the drawing is completed, the cursor is reset in order to get again the icon in the viewport.

UI: New option to display factors as percentages

The option can be changed in the Preferences
in `Interface -> Editors -> Factor Display Type`.
