  17. --NOTE select a painting texture by double clickin with right mouse button--(you can easily "update" the texture mode(linear,nearest,etc.) just by dblcking again )
  18. --TODO BUG if the painting texture is empty it is mostly white but there is some crap in there
  19.  
  20. --TODO
  21. --fix out of map drawing (drawing on edge)
  22. --eraser and clone tool--clone works easily within the same texture?-some GL doc said no...but seems to work fine with my nvidia
  23. --erasing to original texture always needs to get the original map textures which seems to be randomly bugged
  24.  
  25. --make trackbars show the value and double clicking opens an editbox to set it raw(even outside the scale)
  26.  
  27. --myMapfilename(use as the folder) editbox, import export --import is fairly easy
  28. --color picker grid--clicking the big square in current color picker shows a grid window
  29. --include blueprint and editor to edit the values(partially edit in realtime with /commands?)
  30. --change editing mode and blend mode to lists
  31.  
  32. --TODO BUG everything seems randomly inverted or mirrored
