// REVISION HISTORY
// 0.30 properties
// -
// 0.20 initial release
// 0.30 properties release
// - properties panel for editing user-defined "object" properties
// - can link each tile to one other tile
// - keyboard interface
// - fix eraser tool bug (worked in complex cases, failed in simple)
// - undo/redo tools have visible disabled state
// - tiles on higher layers draw on top of adjacent lower-layer tiles
// 0.20 erasable
// - eraser tool
// - fix bug when pasting into protected layer
// - better color scheme
// - internal-use color picker
