octave: doc/interpreter/plotimages.m annotate

annotate doc/interpreter/plotimages.m @ 20335:b439ccc9a162

doc: Improve building of images for the Manual. Switch to using 'qt' as the default toolkit. Stop producing onscreen flicker when building images. Correctly build extended.pdf with new non-recursive build system. * plot.txi: Change sample code for generation of image 15.7 to match the code in plotimages.m * geometryimages.m, sparseimages.m, interpimages.m, splineimages.m: Call new function set_graphics_toolkit which makes sure there is at least something available to do plotting with. Change hide_output() function to call figure() directly with "visible", "off" properties passed to it so there is never a moment when the figure is visible (stops flicker). * plotimages.m: Change directory to working directory where documentation files are kept before executing print with "-pdflatexstandalone". Call pdflatex from within the working directory since that is what it expects. Clean up after pdflatex by deleting auxiliary files. Capture status and output of system command which invokes pdflatex so that it does not spew in to the logs. Change text() command to use '\displaystyle' which looks nicer. Add set_graphics_toolkit function and modify hide_output function as above.
