Sat Sep 26 20:46:18 BST 1998 Adam D. Moss <adam@gimp.org> * app/channel.c app/channel_ops.c app/drawable.c app/floating_sel.c app/gdisplay.c app/gdisplay.h app/gimpimage.c app/layers_dialog.c app/undo.c: Moved the idlerender stuff into gdisplay.c. Implemented idlerender when doing floating_sel->layer, and undoing/redoing layer deletion. idlerender would be useful in many other places for improving interactivity, if it weren't for the following problems: * By definition, idlerender doesn't wait for a gdisplays_update() call before starting work - it just runs in idle time, which due to CPU contention with plugins may not be genuinely available idle time when things are 'noninteractive'. * Most GIMP functions don't know whether they're being run interactively or not. idlerender only makes sense for interactive work. This is why it is currently only applied to those functions which would normally only be activated manually. * Mixing idlerender and drawable_update() / gdisplays_update_area() calls can lead to a region being rerendered twice. Hence, some slogwork is needed before idlerender can be applied in the more general case.
