Added thumbnail image preview functions.
Previews are visible on the L&C&P dialogs as well as in the
drawables/channels/ menus generated for plugins
(see the bumpmap & Mapobject plugins).
PDB interface exists to simply extract a thumbnail preview
of a given size. This is much quicker & more efficient
than getting the image data tile-by-tile if you only need a small
image since a "preview cache" has been implemented. This cache also
reduces the number of times the tiles cached is scanned since smaller
previews are always generated from large ones if they exists and
are valid.
Some possible usages (I don't intend to implement these ideas. Just
suggestions). More plugins using the thumbnail preview (ie any that
use multiple images). Indication of "active image" somewhere.....
Actually almost anywhere a drawable/image name appears.
* app/Makefile.am: build color_cmds, lut_funcs, and pixel_processor
* app/app_procs.c: feedback in the splash screen when loading
parasites.
* app/boundary.c: Optimized find_empty_segs.
* app/brightness_contrast.[ch]
* app/levels.[ch]
* app/posterize.[ch]:
moved pdb and lut calculation code. These files now contain only
GUI functions.
* app/channel.c: Optimized channel_bounds (fewer compares, better
use of registers). Use color_region instead of channel_*_segment
in channel_combine_rect. Optimized channel_combine_ellipse by
skipping pixels inside of the ellipse. Use
pixel_region_process_parallel in channel_combine_mask. Use a
GimpLut in channel_invert, and channel_sharpen.
* app/invert.c
* app/equalize.c: moved the lut functions to lut_funcs.c
* app/gimpdrawable.c, app/gimpdrawableP.h
* app/gimpimage.c, app/gimpimageP.h: removed unused gimpmatrix
variables/includes.
* app/gimplut.[ch]: added new function gimp_lut_process_inline
that operates on a single PixelRegion.
* app/gimpparasite.[ch]: new functions to save/load parasiterc
* app/parasitelist.[ch]: new functions to save/load ParasiteLists
in/from files.
* libgimp/parasite.[ch]: new functions to load/save parasites.
* app/internal_procs.c: get some procs from new location in
color_cmds.h.
* app/pixel_region.[ch]: moved pixel_regions_process_parallel
related functions to a new file.
* app/color_cmds.[ch]: new files for PDB
definitions/implementations of color correction functions.
* app/lut_funcs.[ch]: new files to hold lut creation functions.
* app/pixel_processor.[ch]: new files that contain the
pixel_regions_process_parallel routines. Added some new
capabilities that are currently unused.
Started separating crud out of drawables.
Isolated the id system of images entirely within pdb. Even the
window titles and menus use pointers instead of ids. Should at
least remind people that this is a developers' version. :)
