Blender Git Loki

moved debug print of GPU state to separate file for better reporting (also makes a clean place to put debugging functions)

corrected calculation of the number of addressable texture units

Committed out conflicting part from previous merge. It was no longer possible to compile with Cycles.
Philipp Volguine can you check that out?

* Changing (most) smoke domain settings no longer clears whole domain but just the cache. This way it's easier to try out different settings while playback.
* Copying domain object now also preserves adaptive settings. :p
* Heat/velocity debug visualization (dev only) works again.
* Some code cleanup.

Overlay for Tiled style brushes. The implementation uses openGL
multitexture to minimize texture uploads. The curve strength is written
to a separate texture and modulated with the view texture at runtime.
Unfortunately, I haven't found a way to get a consistent result with the
rest of the brushes because this would require inverting the alpha after
the texture combine operation.

Merge with trunk r48317

Fixes, still not there, fighting with TexEnv currently

Add code to properly support tiled mode overlay. Not functional yet but
I am positive it's a matter of a few glTexEnv tweaks

Merge w/ Trunk: r47143-r48302

Made some changes to the way the snapping system handles different types
of mesh data.
Re-implemented vertex snapping using the new snapping system! There are
a couple of bugs with this recorded in comments for
SnapMesh_snap_vertex.

fixed some brain dead code that only worked by virtue of only being tested for a single case.

Reverted r47493 and r47494 because they are too much trouble to merge for now. (Also re-applied r48249)

Looks like the Blenderplayer was already handling initializing the matrix stack in GPG_Application, so I'm removing it from GPG_ghost.cpp.

Fixing the Blenderplayer for matrix stack and GPU_compatibility changes.

A slightly different way of dealing with the shift problem that doesn't involve a hack. It also changes the design of the layer buttons slightly such that clicking one doesn't automatically reset the others, which I think may be a usability improvement anyway as their purpose is to act like layers, which should be independent of each other. To make up for this I've added a ctrl-click which acts as before, selecting a single layer to the exclusion of others.

Change in the distribution of the layout and change in the limits of the parameters

Clicking on an object in an unselected scene would select the scene but not the object, this is now fixed.

Cleanup: Setting to use mask texture. Only expose texture option if the
option is ticked.

Fix numbers in the color bars not updating when the black and white buttons are pressed.

gpu safety fix, screen join shape was not properly locked
