--- Comment #33 from phaethon eriks00@moon.lv --- pkNormalPressure is UINT as defined in WTPACKET struct at the beginning of wintab.c.
btw, painting with tablet works without reverting user32 change which introduced brush problems with dots.
1) There are still some problems left. If you quickly release and continue a line drawn, then it sometimes becomes 'fixed pressure' until the end of the line 2) After working with some dialogs, menus, switching to other applications it may draw only straight lines (selecting new brush returns normal behaviour) 3) In some situations it stops working until restart of application. E.g. hiding/showing some panels, etc.
But at least it is now usable.
