Set color method for sketches now affects text as well.
Set color method now changes the fill of wedges. Introduced problem with color transition overriding other transitions. Make sure to call setColor after previous sketch transition is finished.
Tried working on hash-wedges. Code is commented out for now.

Changed set color method so it changes the color of text and the fill in wedges.
Sketches can now include wedges of type "hash". This type uses an svg mask to hide parts of the wedge. The mask follows the wedge when it is reflected or moved.

Image viewer test now includes a slider control. Moving the slider changes which image is currently selected, and selecting images with the mouse also changes the slider value.
