FMSLogo Code

Replace constants from winuser.h for virtual key codes with codes that are local to FMSLogo so that KEYBOARDON can work on non-Windows platforms. This also adds some virtual key codes for media keyboards.

Fix an incorrectly documented key code.

More clearly document that KEYBOARDON with one input is for capturing text and KEYBOARDON with two inputs is for capturing keystrokes. Include documentation of the numeric representation of the keystrokes.

Fix some false-positives failures about library routines not being document that were introduced when the Logolib files were lower-cased to make them work properly on GNU/Linux.

Fix a problem with the way the updated icon was exported in the previous revision. Apparently Windows cannot process icons with embedded PNGs (at least Windows XP cannot).

Update the icon to the latest version provided by Jan Grabe.

This includes separate layers for the light green triangle and the polygon decorations on the turtle's shell, and the turtle's shell. It also includes a white background for the text to make it more prominent.

Fix a typo in a comment

Enable WINDOWDELETE (and others) in the screensaver environment.

This makes the screensaver environment closer to the full environment and also unblocks testing the creation of windows on the screen.

Fix a bug that prevented the status window from being seen within the screensaver when STATUS was run.

Fix problems with the WINDOW API regression tests where the "all widgets" tests couldn't fit on the dialog/window and were scattered chaotically when rendered on the screen.

Also fix a problem where the DIALOGCREATE smoke test never showed the dialog box.
