tv_LockDisplay [QUIET] [text]
Locks the TVPaint display and displays a text message. When TVPaint draws a lot of things on the screen, locking the display can significantly increase the working speed (refreshment of the screen takes time). When the drawing is finished you must unlock the display, using the tv_UnLockDisplay command. You can temporarily force a redisplay while the display is locked by pressing on the Space bar (to view the work being done).
