FMSLogo Code

Fix a bug in the Simplified Chinese editor where deleting all text with the "Clear All" was not undoable.

Remove an unused ID in the workspace editor.

Fix a problem with the Chinese editor where, immediately after opening, the user could "undo" the editor's contents back to an empty workspace.

Replace the wxStyledTextCtrl implementation of CLogoCodeCtrl with wxTextCtrl for languages that use multi-byte character sets. Neither wxStyledTextCtrl nor wxRichTextCtrl supported these character sets.

This is a step backward in overall functionality (no styling, no printing, no searching, no paren matching), but fixes the basic blocking problem of not being able to use characters from Simplified Chinese in their programs. Some additional enhancements may be made to it, but not many, since that time would be better spent porting FMSLogo to Unicode.

Add some comments to CWorkspaceEditor::OnRunSelection

Fix some typos in the DLLCALL section when it was rewritten to include the "B" argument types.

Implement feature #119; DLLCALL now supports calling win32 functions that have out parameters.

This is done with a new "type specifier" of "B", whose value is the number of bytes. The out parameters are appened to the return value, which happens to be a list.

Change the default font from "Courier" to "Courier New". This should have been done in version 7.0.0, when I dropped support for Windows 95, as "Courier New" is a more fully-featured font and is standard on the minimum supported operating system of Windows XP.

Make it possible to localize the default font name. This is needed because the default font "Courier" doesn't have glyphs for the Chinese script and so is unsuitable for use on a Simplified Chinese FMSLogo.

Fix Bug #489; Running a Logolib procedure onces again works when the current working directory is on a different drive than the FMSLogo executable.

The problem was that the base directory was extracted without the drive letter, so it was treated as relative to the current working directory's drive. If the user changed the working directory to a different drive, then the logolib procedure would be loaded with the correct path on the wrong drive and fail.
