sixeltek terminal: transparency and background options

In file included from term.h:170, from term.c:1311: ../term/tek.trm: In function ‘SIXEL_text’: ../term/tek.trm:817:57: warning: self-comparison always evaluates to true [-Wtautological-compare] 817 | if (n < b_xsize-1 || pc != '?' || k == k) { /* do not output empty lines */ | ^~ What is the intent here?

The clear screen escape sequence is sent by term_reset(), which is invoked when you either (1) made another plot, (2) change the terminal type or settings, or (3) exit the program. I believe the intent was that the plot would remain visible on your screen until you did one of those things. However the "set output" / "unset output" commands are treated as changed the terminal settings. term_reset() appends the clear screen sequence to the output file when it is closed. This is/was probably not ideal...

Improvement of datablock size retrieval performance

The difference will go away if you tell the program to treat a coordinate whose value is found to be NaN the same as a coordinate that is missing from the input data. set datafile missing NaN The next question is obviously "why does $2*$1/$1 evaluate to NaN while $2+10 apparently does not?". Good question. When reading in a line of data, the program returns an error flag DF_MISSING to indicate that a required coordinate is missing. The test for that condition is trivial if the coordinate is simply...

Sorry, that should have been commit 7f0dfb24
