Fix Cycles OSL script node not working in shader using bump, after node type refactoring.

Fix T48908: gray out Cycles motion vector pass if motion blur is enabled, doesn't work then.

Cleanup: warnings

Cleanup: unused brush DNA

Cleanup: spelling

Cleanup: use BKE naming convention for object materials

Also remove unused 'material_from' function (which isn't very useful).

Fix copy-materials resetting objects material indices

Cleanup: remove completely call to test_object_materials in BKE_mesh_new_from_object.

Don't know why this was ever added to start with, BKE_mesh_new_from_object shall never affect ob->data!

Fix T48898: shaders are removed from metaballs on cycles render.

Note that issue has several levels here actually, first one was metaball's materials
not being properly copied into new mesh (code was commented out because of some crash it
seems, made it a bit closer to mesh one and got no crash at all...).

Then, we were calling test_object_materials when ob->data is actually *not* new tmpmesh!

Will remove this call completely in next commit (to make it easier to bisect), I cannot see
any case where object would be assigned with newly generated tmpmesh in this func.

Fix own error in recent heap update

OpenSubdiv: Initial work to support UV maps in textured OSD viewport

A bit work in progress, currently the following limitations:

- Texture shading only, Material shading will come later

- No UVs subdivision yet

- Always uses active UV and currently changing active UV will
not properly update the viewport.

Well, need to start somewhere :)

OpenSubdiv: Wrap OSD's TopologyRefier with own struct

This is a way for us to store extra data, such as UVs which we can
collect now on topology refiner stage.

Fix T48897: Flatten brush fails on first stroke

The flatten brush depended on accumulate being disabled,
Adding dynotopo support for accumulate caused problems for this tool (see T44390).
Enable for existing files.

possible fix for crash mentioned in T48887 - Adjust the depth min to the object scale

BMesh: improve BM_face_splits_check_legal

- remove edge scaling, instead avoid checking intersections with connected edges.
- replace local line intersection functions with BLI_math
- center the projection for more precise calculation.

Update tracker URL

Also wrap line-length

Add 'reload' function to libraries' RNA API.

Improved warning message when creating empty export file

Fix (IRC reported by Sergey) assert regarding icon_id of newly copied datablocks.

BKE_previewimg_copy() would simply copy PreviewImage's icon_id, without bothering about
ID one.

When we duplicate an ID, we want to reset its icon_id to zero (and regenerate it on-demand),
not keep same icon_id as original, so added new BKE_previewimg_id_copy helper to handle that.

Usual i18n/UI messages fixes...
