<p>ASSDraw3 is a tool for designing shapes to be used in ASS subtitle file. \
<p>To add lines or curves, initiate the draw mode by clicking on the drawing tools. \
Then, either click on empty space or drag from an existing point to add the new lines/curves. \
Control points for Bezier curves are generated once you release the mouse button. \
<p>To modify shapes, drag their points (squares) and control points (circles) in the drag mode. \
<p><b>Some tips & tricks:</b> \
<ul> \
<li> Set background image by dragging image file from explorer onto the canvas \
<li> Use the Shapes Library to store your drawings \
<li> Ctrl-Z for undo, Ctrl-Y for redo \
<li> Use your mousewheel to zoom in/out (PageUp/PageDown keys work too) \
<li> Dragging with right mouse button moves the drawing and/or background image around. \
<li> Double clicking with right mouse button for popup menus. \
<li> Holding shift key while in the draw mode temporarily switches to the drag mode \
<li> The shapes origin (coordinate [0, 0] depicted by the small cross) is draggable \
