fix [#36247] Modifier Ocean (Geometry in Displace)- Subdivision Surface
regression in 2.68

fix [#36248] Crash using factor input on color mix node.

Allow creation of mask nodes in compositor with drag&drop of mask datablocks

Also remove superfluous "deselect all" operation in drag&drop for images

fix regression in 2.68 [#36240] Painting Undo Enable Face paint Crash

optimization:
- halve the number of allocs in layerInterp_mdeformvert list creation.
- use direct loop access in emDM_copyLoopArray

optimization: lazy initialize EditDerivedBMesh members vertexNos, polyNos.

also add polyCos array which cache's face centers, gives overall ~20% speedup to drawing on a high-poly mesh in face-editmode.

cloth: Fix [#36224] Cloth Simulation Doesn't Work on Rearranging Modifiers

Don't return imediately when simulation has changed.
It's not needed and prevented proper initialization on startframe when
simulation changed.

old todo, rotate around individual origins now supports connected face/edge islands.
previously this gave very odd/annoying results, see bug reports [#36134], [#35419]

transform was flushing the selection (inline), now skip this and use the selection as-is.
flush the selection on entering editmode instead (since the selection mode can be changed with another mesh).
is other tools leave the selection incorrectly flushed, those will need to be fixed so transform works as expected.

Show full image node detail buttons in the sidebar. The image nodes in compositor, cycles and texture nodes were showing a very reduced version of the image data block UI, based on the idea of fitting it
into the confined space of a node. However, in the side bar panel there is no reason to limit the buttons. In fact it is very helpful to have this UI available, otherwise users have to have an image
editor or (BI) texture buttons window next to the node editor to access these image details.

add support for BM_mesh_calc_face_groups to use vertex connectivity (not currently used yet)

Fix crash in adding a new mask point after subdividing an inactive spline

add_vertex_extrude relies on active spline for containing an active point

_MSV_VER should be _MSC_VER

code cleanup: de-duplicate BLI_ghashIterator_new/init and disable unused text undo print function.

correct switch statement: image_listener NC_GEOM was falling through to NC_OBJECT

snap to cursor (offset option) added for UV's too.

code cleanup: compiler warnings

Merging r58464 through r58474 from trunk into soc-2013-depsgraph_mt

Fixes for recent Wlimit stuff, which makes strict gcc freak out

Code cleanup / Cycles:
* Remove useless else branch, after recent changes.
