== Ptex ==

Changed the internal ptex format to always use subfaces

* Changed MPtex to references MPtexSubfaces, each of which is a quad with U and V resolution and it's own ptex data pointer.
* This format is basically the same as what triangles were already using, but now quads work the same way.
* This format is also closer to the way multires grid data was already stored.
* Ptex loading (and saving, once that's implemented) requires some extra work to convert to the internal format, but everywhere else the code is much simpler.
* Fixed undoing ptex changes on a different multires level from where they were painted.
* Ptex paint now always uses an all-quad DM (generated with one level of ccgdm simple subsurf.) This is a bit ugly, just stuck on the end of calc_mesh_modifiers. This is only done if there's no multires or subsurf modifier at the end of the stack.
* Resolution editing is disabled for now, will restore it in next commit

Merged GPUDrawFlags into DMDrawFlags, cleaned up DMDrawFlags

For ptex-resolution editing mode, show a tiled pattern representing ptex texels.

Fixed anchored and drag dot stroke modes.

* Vpaint mesh restore

svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r31183:31296

Controls for setting local ptex resolution

* Fixed various problems preventing the old paint mask mode from showing correctly, repurposed it for editing ptex resolution
* Added an operator that resizes a ptex face (uses bilinear interpolation)
* Added a new ptex panel that only shows in paint mask mode
** Two buttons, Half and Double, that cut the U/V resolutions in half or double them, for all selected faces
** For more precise control, the U and V resolutions can be individually selected for a single face
** For triangles, the resolution of individual subfaces can be set
** Lastly, the resolution of the active face is shown (one resolution for each subface)
** The UI is not good, but the underlying code is there at least.

Fixed some python merge errors in my branch.

* Enabled undo for multires
* Changed texture interpolation to linear

Accidentally left in a statement before declaration error

svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r31091:31183

== Ptex ==

* Enabled drawing of ptex on a multires mesh
* Enabled ptex painting on a multires mesh

Note that the multires level doesn't effect the ptex resolution; multires has no effect on ptex other than making the display smoother.

== VPaint ==

Removed a bunch of unused code

Undo support

== Ptex ==

* Removing some old vpaint/multires stuff that is obseleted by ptex

== Paint ==

* Missed a few things in my last commit

Paint overlay

* Added a new vpaint input that samples an image rather than using the
brush color

* The image is displayed as a translucent overlay in vpaint mode
** Can be toggled on and off in the UI or with IKEY

* A color can be marked as transparent so that it will not affect the
brush color
** There's a tolerance value to set how close colors have to be to the
transparency color

* The image overlay can be moved with G/S/R when its enabled

* For now only enabled in vpaint mode, should be enabled for texpaint too

== Ptex ==

Fixed unitialized variable reported by mariusz

== Ptex ==

* Small bugfix for my previous commit, broke ptex generation

svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r30887:31091

== Ptex ==

Fixes for triangles

* the quad-mesh-with-triangles example file from ptex contains subfaces with
non-matching resolutions; changed the internal MPtex format to store
separate resolutions for each subface

* changed ptex drawing to give each subface its own texture

* various fixes to the loading and painting code to support triangles

* small change to the ptex build files, hopefully fixes and MSVC issue
