<h1>Sokoban Bitmap Editor</h1>
<p>This javascript applicaiton is used to generate highly optimized jack code for drawing a 16x16 bitmap to the screen.</p>
<p>Using the mouse, click the desired cell to mark/unmark it. You may use 90 degrees rotation and vertical mirroring by<br>
clicking the appropriate buttons.</p>
<p>When you are finished drawing, you may select function type and enter function's name.</p>
