The main task on today's agenda was to start preparing the Editor for the implementation of multiple tile sizes (currently I hope to implement 16x16 tiles, 32x32 tiles, 64x64 tiles, and 128x128 tiles).
The first task was to change the display cursors and tile selection cursors from bitmap images into Blitz-drawn rectangles and lines (which should also allow for customisable colour schemes).
That done, I started wading through the routines one by one, tweaking those that didn't utilise my handy "tilesize" variable, and making sure those that did no longer assumed the tiles were 32x32.
