   - *Desc*: Draw a stroke from the last position to (x, y), with strokewidth controlled by `drawing` (`true`->`tb.drawing_width`, `false`->`tb.erasing_width`).

   - *Post*: A drawcall `glDrawArrays` has been issued.
   - *Notes*: Undefined behaviour if `draw` has never been called, or the precondition is violated.
 
-  Issues a drawcall (`glDrawArrays`). 
-  The argument is unused. 
-  Correct usage first calls `draw`, then calls `redraw` without changing the state of `GL_ARRAY_BUFFER` in between (typically, framebuffer and texture bindings are changed in between).
