FMSLogo Code

Fix a bug where printing a very long line did not end up with the commander history scrolling to the bottom.

Fix a regression that was introduced during the upgrade to wxWidgets 3.1.0 where the commaner input would retain its horizontal scroll position when its text was replaced. This was especially bad when a long line was replaced by a short one, in which case the new text might not be visible at all.

Fix a build break when compiling with WX_PURE.

Add UI automation to the editor tests to relieve some of the manual burden when running a full test pass.

Add UI automation to the STEP tests to make it easier to run a full test pass.

Fix bug #319; SETACTIVEAREA now throws a recoverable error when given points that define a zero or negative area rectangle. Before, the error was not recoverable.

Also extend the ERRACT test infrastructure to support testing giving a command bad input (before, it requires that the bad instructions output a value). This involved rewriting some of the existing callers.

Fix the test to pass integers to SETACTIVEAREA, now that SETACTIVEAREA throws an error when given non-integral numbers.

Fix the example for :ERRACT to match how FMSLogo behaves.

Fix an unnecessary warning when running IFTEST by replacing a call to IF with IFELSE. The call was intended to act like IFELSE, but was not testing the IF-becomes-IFELSE behavior.

Fix an off-by-one bug that prevent cnv_node_to_intnode() from returning an int node when the number was FIXNUM_MAX.
