Fixed a minor bug in the MiniMap code which meant that the code had no default values to work from (and thus, was appearing completely black).
Decided to pluck some small tasks off my To-Do list, specifically the Tool Tips system which will provide prompts on using the various tools (after a suggestion by Muttley). At the moment, the program prints a line of text on the Status line, but this is usually lost whenever another action is performed (the Status area is used continually for prompts and messages).
Then I hit upon the idea of adding an extra panel to the Info / MiniMap area of the screen; whenever the user needs prompts, they simply click the tabber and follow the instructions. Full functionality will come later, but already the panel is fairly intuitive to use.
Addressed a small bug in the Grab Panel, which meant that thumbnail images were being generated in 32x32 tile mode, then started work on the Fetch Tile routine (which will hopefully move the tile selection cursors intelligently).
