Getting On With It With David Oberlin

Update:

• Resizing is working to scale.
• Tile selection is now using transparency.
• Tileset Importer is now a class instead of a big, big function.
• Tilemaps are now composed of same tile class as tilesets.
• Images use vectors instead of array pointers for storing colour data.

I'm going to make a few changes to the UI from the 0.1 builds in that drawing and selecting will be decoupled from being hermetically linked to the mouse buttons and instead given their own modes.
