FMSLogo Code

Rework the description of LABEL, mostly to document that legacy typefaces don't support being rendered at an arbitrary angle.

Update the version of DocBook that is used.

Add clearer explanation to LABELSIZE based on the investigation for the fix of Bug #469--specifically the interaction between LABELSIZE and the turtle's orientation.

Implement feature #89; Make -F (with no -W or -H) start FMSLogo maximized and make the drawable surface as large as possible to match the screen window.

Add regression tests for LABELSIZE, including tests for bug #469.

Fix bug #469; LABELSIZE no longer changes its output depending on when LABEL was last run.

Implement feature #89; Make -F (with no -W or -H) start FMSLogo maximized and make the drawable surface as large as possible to match the screen window.

Further improvement for feature #89; When FMSLogo is started with -F, then whenever its maximized, reset the splitter position to show the entire screen window, despite where the user may have moved it.

Implement feature #89; Make -F (with no -W or -H) start FMSLogo maximized and make the drawable surface as large as possible to match the screen window.

Fix a typo where "height" was reported as "width". Also document the interaction between -F and -W/-H.
