FMSLogo Code

Translate "less/greater than or equal to" as "major/menor o igual que".
This is how Wikipedia and a Spanish C++ manual refers to these operators.

Translate the documentation for the Turtle Movement commands to Spanish.
This translation was based on Rosario Ruiz's translation of the MSWLogo manual.

Fix a typo "selects to the" -> "selects the".
Also move the description of an example into a <para> and other small changes.

Translate the documentation for the "Multiple Turtles" commands into Spanish.
This was based on Rosario Ruiz's translation of the MSWLogo manual.

Fix the Spanish translation of NOBITMAPTURTLE.
It was "PonFormaTortuga", which means the same thing as PonForma, the translation for BITMAPTURTLE. It doesn't make sense that "ponforma" should mean both bitmap the turtle and remove the bitmap. To correct this, I chose an opposite of "pon", which is "quita". The strange "PonFormaTortuga" was added by COPYDEF for backward compatibility. It may be removed in a future version.

Reorganize the content of SETTURTLEMODE to improve clarity.

Clarify that TURTLE outputs a number, not a turtle.

Clarify the final sentence of the description of SETTURTLE, which describes when a turtle gets the shared pen.
Also clarify the examples a little.

Translate the front-matter for the Graphics chapter to Spanish.
This translation is based on Rosario Ruiz's translation of the MSWLogo manual.

Update the polygon demo to use multiple colors when drawing the sphere.
This demonstrates the feature that each surface can have a different color, which is something that I had forgotten FMSLogo supported. Putting this into DEMO makes it more discoverable.
