FMSLogo Code

Update LABELCIRCLETEST so that it doesn't leave a dot in the middle of the screen. This dot came about as a result of fixing bug #1602928 (Turtle only draws a dot when it *leaves* a position).

Update the baseline based on new tests that were added.

Add benchmark for 6.20.0.

Fix bug #1959250; SETBITINDEX no longer changes BITINDEX on bad input.

This was fixed when I added support for unlimited bit cuts.

Add some out-of-memory tests, now that SETBITINDEX can create an arbitrary number of bitmaps.

Implement the rest of feature request #1542399; FMSLogo is no longer limited to 1024 bitmaps.

This resulted in making the binary 1KB smaller, probably because I noticed that a few function parameters were also zero, and eliminated them.

Implement part of request #1542399; FMSLogo is no longer limited to 1024 turtles.

Add a regression tes for bug #1959250, which is that SETBITINDEX has side-effects when given bad input.

Implement part of request #1542399; FMSLogo is no longer limited to 1024 turtles.

Add a test for when allocating the array fails.
