FMSLogo Code

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.

Minor improvements to the documentation for POLYSTART and POLYEND:
* vertices made in PENUP mode are ignored
* clearscreen will erase any polygons
* used clearer, more direct wording

Fix bug #477; POLYEND now throws an error if the polygon has two vertices (same as if the polygon has one vertex).

This revision also includes many new regression tests for the polygon API.

Fix a reference to a bug number in the source code (the bug numbers changed when SourceForge.net was bought by DICE and they redid the database backend).

Change an #if into an #ifdef to fix a compiler warning

Remove the call to GetVersionEx() and everything which depends on it. The only remaining use of this was to determine if HALFTONE was supported by SetStrechBlitMode(). On Windows 95, this is not supported and so COLORONCOLOR was used. Since FMSLogo no longer supports Windows 95, it can assume that HALFTONE is supported.

This was done to clean up the code, remove untestable portions, and remove unnecessary platform-dependent code to assist with the GNU/Linux port.

Remove some unneeded #defines that duplicated what should have been in windows.h, but now generated compiler warnings.

This was needed to be able to compile the screensaver with an old version of MinGW whose libc didn't include instructions that weren't implemented in the original Pentium CPUs. As of version 7.0, FMSLogo no longer supports those machines or that compiler, so #defines can be safely removed (and the compiler warnings along with them).
