install_deps.sh: point to newer own OSL rev (should fix issues on recent distro featuring recent ilmbase libs).

Fix T46793: VSE OpenGL renderer crashes when using grease pencil

Own regression in recent speedup commit.

Fix T46784: Connect vertices (follow up)

Another fix for a slightly different case from the original report, to give better orientation.

Vertex normals influence on the orientation is now scaled by the alignment with the cut direction.

Also use face normal instead of loop normal which can be unreliable when the corners edges are co-linear.

Fix T46764: Crash toggling region + fullscreen

Clear timer on region duplicate, avoid double free

Fix crash changing screen + region overlap fade

Usual i18n messages fixes...

Fix/enhance BKE_mesh_validate_arrays.

Aside from some minor cleanup, this commit:
* Fixes checking twice for multiple usage of same vert by a same poly.
* Fixes handling of ME_VERT_TMP_TAG vert flag by that check (there was no guaranty
that flag was cleared for a poly's vertices before we start checking).

Speedup OpenGL sequencer animation rendering

The idea is to avoid having roundtrip from byte to float and back to byte buffer
and use render result's byte buffer to store result of sequencer rendering.
This actually matches to what regular render pipeline is doing and this gives
around 2-3 times speedup of sequencer export on a simple scenes.

ImBuf: Fix typo in duplicating float z buffer

Remove unused arguments from RE_WriteRenderViewsMovie()

Followup to previous commit: similar thing was happening for multiview case

Color management: Skip doing float->rect conversion twice when rendering animation

This is something what IMB_colormanagement_imbuf_for_write() is intended to do.

Gives around 40% speedup in test wile with OpenGL render and about 20% when
rendering simple cube scene animation.

Fix own error w/ camera-dof in GL-render commit

GHOST: rename suffix X11 to Unix for non X11 files

We may use these for Wayland or SDL back-ends.

Cleanup: typos

minor cleanup: typo

Fix T46784: Connect vertices uses odd orientation

Use connected faces to calculate the paths orientation
when normals are aligned with the direction.

Add missing newlines for debug prints

check compute shader support for OpenSubdiv

Built into OpenGL 4.3, or 4.2 plus ARB_compute_shader extension.
