* libgimp/gserialize.c * libgimp/gserialize.h: Changed the enum values to allow for simpler future expansion. * libgimp/parasite.c * libgimp/parasite.h: s/persistant/persistent/. new accessor functions for parasites. #defines for new flags. * app/paintbrush.c: added timeing code for brush strokes. It is #ifed out, and is only valid for shift clicks. * app/parasite_cmds.h: fixed a warning * app/parasitelist.h * app/parasitelist.c: added _for_each and _length functions * app/gimpdrawable.c: set the dirty flag when adding or removing a persistent parasite * app/gimpimage.c: set the dirty flag when adding or removing a persistent parasite. Fixed bug and removed debug statements in merge_down. * app/xcf.c: save and load resolution, parasites, and tattoos. * app/main.c: updated the deserialize test. * plug-ins/tiff/tiff.c * plug-ins/gif/gif.c: use PARASITE_PERSISTENT define instead of 1 * plug-ins/bmp/bmp.c * plug-ins/bmp/bmp.h: declare some struct variable as extern. * app/paint_funcs.c: Lots of optimizations aimed at speeding up painting. Should see a 2-4X speed up on most painting (depending on paint modes, brush size etc.) * app/drawable.c: check for NULL drawable in drawable_ID. this stops us from being crashed by ill-behaved plug-ins
