== Ptex ==

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.
