This is v1.1.5 of the Colorizing HC stuff, replacing the previously distributed versions. At the heart of the stack is the colorizeHC XCMD, which supports colour backdrops in Hypercard – supporting a surprising variety of colour effects in standard Hypercard. However, a stack provides other features. With some simple amendments to your stack, it will send extra messages to indicate when colour or windows should be added. It will maintain a list of windows over a card, and move then if the window moves and close them when the card closes. For read-only stacks it maintains a number of global variables, saved and restored for each stack – supporting stacks that change the appearance of particular cards when they are on the screen, but do not wish to save the data when Hypercard terminates. The same mechanism can be used generally to skip some of the initialisation process of a stack when subsequently resuming it.
This version still contains v1.0 of the XCMD, but has many extensions of the support scripts and fixes a few bugs. The XCMD stack itself can be more easily distributed as a run time system, without its support stacks.
