FMSLogo Code

Add the changes for 6.17.0.

Integrate some tests for GIFSAVE, GIFLOAD, and GIFSIZE.

Remove the UserType global variable. Now that I understand how the SHELL_CONTEXT registry key works, I can just rely on calling SetShellVarContext, instead. This simplifies the installer logic.

Fix bug #1713912; Uninstalling FMSLogo as a limited user now unregisters the file association so that double-clicking on .lgo files works if FMSLogo is later installed by an administrator.

I fixed this bug by simplifying the installer script to use SHELL_CONTEXT as the registry hive, instead of checking the UserType and then executing the same logic on a HKCU or HKLM depending on its value. Using SHELL_CONTEXT does exactly the same thing in less than half the code.

Fix bug #1813051; Saving an image with an non-full active area works once again. This bug was introduced in 6.16.0.

Add BITSAVE.WITHACTIVEAREA, a regresion test for bug #1813051.

Fix a bug where CATCH "ERROR wouldn't catch errors on non-English versions of FMSLogo because the error was thrown as "ERREUR" or some other localized string and wouldn't compare equally with "ERROR.

Transfer some of the German translations from startup-1033.logoscript to localizedstrings-de.h.

Fix a bug introduced in the previous revision where I changed a compare_node() to a call to Error.GetNode(), instead of a call to Error.Equals().
