 This tool allows you to draw free
 hand with the currently selected brush
 and color/pattern.

 To use the Pencil, just press and hold
 the mouse button. Draw with it like
 you would a real pencil. When your
 done just release the mouse button.

 This tool can be constrained at any
 time you are using it by pressing
 and holding the Shift key.

 If the Stencil function is on then
 drawing will only occur within the
 stencil.
