#called from pkg_chooser.sh
#package to be previewed prior to installation is TREE1 -- inherited from parent.
#/tmp/petget/current-repo-triad has the repository that installing from.
#100821 bug in Lucid 5.1, /tmp/pup_event_sizefreem had two identical lines.
#101221 yaf-splash fix.
#120101 01micko: jwm >=547 has -reload, no screen flicker.
#120116 rev. 514 introduced icon rendering method which broke -reload at 547. fixed at rev. 574.
#120203 BK: internationalized.
#120504 if no pkgs in category, then when click in window in main dlg, comes here with TREE1="".
#120504 select correct repo when have chosen a pkg from multiple-repo list.
#120604 fix for prepended icons field.
#120811 category field now supports sub-category |category;subcategory|, use as icon in ppm main window.
#120827 if pkg already installed, do not examine dependencies (doesn't work).
#120903 ubuntu, have lots pkgs installed, check_deps.sh takes ages, remove for now, need to rewrite in C.
#120904 "examine dependencies" button did not create any /tmp/petget_missing_dbentries-*, workaround.
#120905 better advice if too many deps. 120907 revert.
#120907 max frames increase 5 to 10. Note, precise puppy gave 72 deps for vlc, which would require 10 frames.
#130511 popup warning if a dep in devx but devx not loaded.
