Bit of a large checkin this - it's basically three things:
1 - GimpModules using gmodules to dynamically load and
initialise modules at gimp start of day.
2 - Color selectors now register themselves with a color
notebook.
3 - progress bars have been cleaned up a bit, so now have
progress indictations on all transform tool and gradient
fill operations. Not done bucket fill, but that seems to
be the next candidate.
New directories:
* modules/: new directory for dynamically loadable modules.
New files:
* modules/.cvsignore
* modules/Makefile.am
* modules/colorsel_gtk.c: GTK color selector wrapped up as a
color selector the gimp can use.
* app/gimpprogress.[ch]: progress bars within gimp core, either as
popups, or in the status bar. This is mainly code moved out
of plug-in.c
* app/color_notebook.[ch]: color selector notebook, implementing
very similar interface to color_select.h so it can be used as
a drop-in replacement for it.
* libgimp/color_selector.h: API color selectors need to implement
to become a page in the color_notebook.
* libgimp/gimpmodule.h: API gimp modules need to implement to be
initialised by gimp at start of day.
Modified files:
* Makefile.am: add modules/ to SUBDIRS
* libgimp/Makefile.am: install gimpmodule.h and color_selector.h
* app/gimprc.[ch]: recognise module-path variable.
* gimprc.in: set module-path variable to something sensible
(currently "${gimp_dir}/modules:${gimp_plugin_dir}/modules").
* app/Makefile.am: build color notebook and gimpprogress
* app/app_procs.c: register internal GIMP color selector with
color notebook.
* app/asupsample.c: call progress function less frequently for
better performance.
* app/asupsample.h: progress_func_t typedef moved to gimpprogress.h
* app/blend.c: make callbacks to a progress function
* app/color_area.c: use a color notebook rather than a color selector
* app/color_panel.c: ditto
* app/color_select.c: export color selector interface for notebook
* app/color_select.h: color_select_init() prototype
* app/flip_tool.c: flip the image every time, rather than every
second click.
* app/interface.c: move progress bar stuff out to
gimpprogress.c. Make the code actually work while we're at it.
* app/interface.h: move prototypes for progress functions out to
gimpprogress.h
* app/plug_in.c: load and initialise modules (if possible). Move
progress bar handling code out to gimpprogress.c
* app/plug_in.h: keep only a gimp_progress * for each plugin, not
a whole bunch of GtkWidgets.
* app/scale_tool.c
* app/rotate_tool.c
* app/shear_tool.c
* app/perspective_tool.c: progress bar during operation.
De-sensitise the dialog to discourage the user from running
two transforms in parallel.
* app/transform_core.c: recalculate grid coords when bounding box
changes. Only initialise the action area of the dialog once,
to avoid multiple "ok" / "reset" buttons appearing. Undraw
transform tool with correct matrix to get rid of handle
remains on screen. Call a progress function as we apply the
transform matrix. A few new i18n markups. Invalidate
floating selection marching ants after applying matrix.
* app/transform_core.h: transform_core_do() takes an optional
progress callback argument (and data).
* plug-ins/oilify/oilify.c: send progress bar updates after every
pixel region, not only if they processed a multiple of 5
pixels (which was quite unlikely, and therefore gave a jerky
progress indication).
