* consistency
 texture editor & 3d editor update each other
 check normal updating (texel area updating for mipmapping)
 disable hotkeys for greyed items (win api ?)
 enable/update menus
 dialogs remember values (between sessions?)
 go through defs.h, order and rename
 merge spline & splinecheck etc. in sweeps

* data structures
 move ponv llnodes into polygon
 CShape: animation of CShapeDatas
 CAnim: can step through frames without Play

 selections array or ll? ll for current (others prolly won't change)?
 CUndo inherits CClipbrd ?

* transformations
 custom matrix transform
 path/box deformations - tesselate if area * 2
 bump grid from heightmap file

* modelling
 blobs
 spline curve, patch, xsectional modeller (as in imagine)

* editors
 split edge in spline curve editors
 load tga, bmp, jpg, png, tif
 hierarchy / seln
 3d paint onto texture
 save a skin mesh to paintover (quake)

* windows
 multi file select in open, multiple file formats
 ini file
 info panel / status bar
 tree view for hierarchy
 cursors (eg hourglass)
 directdraw rather than createdibsection?

* formats
