Merge branch 'blender2.7'

Cleanup: style

Cleanup: use unsigned char (change previous commit)

Cleanup: warnings

Fix T59866: UV editor: no circle select.

Fix T57861: Object.ray_cast (and all RNA functions using "ob->runtime") broken in Blender 2.80

In fact, we can get valid depsgraph 99% of time from current context.

Still added extra optionnal depsgraph parameter just in case (and also
for future, when we might be handling much more temp depsgraphs).

GPU: Add another driver to the list of unused_fb_slot_workaround

I start to think that an automatic detection would be a better solution.

Fix T59505: Knife tool cut preview line becomes black

The real reason for the problem is still unknown, but this solution adds less overhead than rBdafaa6f22881.

Revert "Fix T59505: Knife tool cut preview line becomes black"

This reverts commit dafaa6f22881419ac55f2f3fe3de9ac4023aa108.

GP: Remove duplicate code moving to single function

Fix/cleanup typos and such in UI messages (and some comments).

Build script: Don't use external Pugi for OSL

Now, things are becoming REALLY confusing. The script does build
pugi, but is never telling OIIO to use an external one. Which makes
it to use a bundled one.

Trying to link OSL to a different version of pugi causes a lot of
linking errors.

Interestingly enough, that was me who made OSL to use external pugi
to solve configuration problem. But now i can not reproduce that
anymore.

Ideally we would either link everything against our pugi, or not
compile it at all.

Fix/cleanup another bunch of UI messages issues.

Also (mostly in comments): behaviour -> behavior (we use American English).

Fix T59722: stencil texture overlay not working on macOS.

Fix T59799: crash entering texture paint mode.

Fix floating panel (HUD) applying DPI incorrectly

ARegion.sizex/y should never have DPI factor applied. For regular panel
regions, DPI will be applied in region_rect_recursive already, causing
it to be applied twice when region size is set dynamically (= based on
content dimensions).

Fix and workaround for i18n messages extraction code.

Cleanup: First batch of UI messages fixes (typos, final points...).

Also contains some code typo fixes (mostly, adtaptative -> adaptive,
former is nearly innexistant in English, let's stick to simple valid
words ;) ).

Avoid creating & registering zero sized AZones

Would allocate memory for AZones and register them even if their
coordinates/bounding-box was all 0, meaning they're not visible and not
interactive.

GP: Small changes to help text
