FMSLogo Code

Added an explanation of how the array's mutable nature can lead to aliasing bugs, where modifying an array ends up modifying other references to it.

This confusion was discussed in the Open Discussion forum.

Update the documentation for READWORD to more clearly explain how characters can be "processed" and "preserved" and also remove the incorrect suggestion that a programmer can determine exactly what was entered by using BACKSLASHEDP.

This change was motivated by posting on in the Open Discussion forum.

Speed up the test pass by working around a performance regression when the commander is resized when there is a lot of history. The change is to populate the history with a pre-determined amount of text and create a new test case for when there's a lot of history, which won't be integrated into the history until the bug is fixed.

Update the expected test log to include the results of some new tests which were added that cover POLYSTART, POLYEND, SCROLLX, SCROLLY, DIALOGFILEOPEN, and DIALOGFILESAVE.

Fix an assert failure in wxWidgets 3.1.0 when running "FULLSCREEN SPLITSCREEN" repeatedly within a line of execution (such that wxWidgets didn't destroy the old commander).

Ban the word "issue" and use "run" or "call" instead within the FMSLogo manual. "Issue" was used with exactly the same sense as these words and there's no reason to introduce a new word for an existing notion.

Further improve the performance of REPEATWORD by recursively applying the O(log N) strategy.

Improve the performance of REPEATWORD by doubling the word until the largest power of two under :repcount.

Remove an extraneous sizer flag that caused an assert failure in wxWidgets 3.0 whenever SELECTBOX was run.

Remove extraneous sizer flags that caused an assert failure in wxWidgets 3.0 whenever QUESTIONBOX was run.
