Sat Aug 21 01:06:53 BST 1999  Adam D. Moss  <adam@gimp.org>

	* app/nav_window.c: Navigation window shows checkmarked alpha,
	also previews correctly for greyscale images now.

Sat Aug 21 00:07:37 BST 1999  Adam D. Moss  <adam@gimp.org>

	* app/nav_window.c: Improved pointer tracking when
	dragging navigator rectangle - less lag.  Enabled hourglass
	when computing first thumbnail.

1999-08-20  Michael Natterer  <mitschel@cs.tu-berlin.de>

	* app/Makefile.am
	* app/gimpdnd.c: new file. Contains a function which creates dnd
	preview icons for all kinds of drawables.

	* app/gimpdnd.h: added the new dnd types.

	* app/channels_dialog.c: same dnd functions as in the layers
	dialog. Fixed channels_dialog_flush(). Code cleanup.

	* app/layers_dialog.c: enabled dnd for layer masks.

	* app/disp_callbacks.c
	* app/interface.c: dnd code generalization. The toolbox and the
	display accept drop of any kind of drawable now.

	* app/gimage.h
	* app/gimpimage.[ch]: new function gimp_image_position_channel().

	* app/layer.[ch]: new function layer_mask_get_layer().

	* app/apptypes.h: added InterpolationType enum.
	* app/gimprc.[ch], app/preferences_dialog.c: replaced
	cubic_interpolation flag with interpolation_type variable.

	* app/pixel_region.[ch]: added pixel_region_has_alpha function.

	* app/paint_funcs.c: rewrote scale_region.  It now behaves
	correctly on images with alpha, no longer leaves an artifact on the
	right edge of images when scailing up, and runs signifigantly
	faster.

committed already just as a safety measure in case my disk crashes...
ChangeLog entry will be written when it is ready.

1999-08-19  Michael Natterer  <mitschel@cs.tu-berlin.de>

	* app/Makefile.am
	* app/gimpdnd.h: new file containing the dnd data definitions.

	* app/disp_callbacks.[ch]
	* app/interface.c: drop layers on the toolbox to create a new
	image and on the display to copy it to the image's layer stack.

	* app/layers_dialog.c: drop layer on the "New" button to create an
	empty layer with the dropped layer's properties, to "Duplicate" to
	duplicate it and on the trashcan to delete it.
	Thanks to Andy for the ultra-cool dnd preview pixmap patch.

	* app/layer.[ch]
	* app/undo.c: renamed layer_mask() to layer_get_mask(). Prototyped
	some function headers.

	* app/disp_callbacks.c: Wheelmouse stuff: Shift+wheel scales the
	display.

	* app/airbrush.c
	* app/eraser.c
	* app/paint_options.h
	* app/paintbrush.c
	* app/pencil.c
	* app/tool_options.c: moved the "Incremental" toggle to the
	PaintOptions structure because it is used more often now.

* tools/pdbgen/pdb/drawable.pdb: #include "channel.h" and "layer.h"
for GIMP_CHANNEL, GIMP_IS_LAYER, and GIMP_LAYER #defines

The rest of these files are generated from the fresh pdbgen run

        * data/brushes/vine.gih
        * data/brushes/pepper.gpb: new files, a sample hose
        and a sample pixmap brush

        * docs/gpb.txt
        * docs/gih.txt: vague description of the current pixmap
        brush and hose formats

        * app/gimpbrushhose.c
        * app/gimpbrushpicmap.c: use the brush spacing info now

Wed Aug 18 22:49:31 1999 Adrian Likins <alikins@redhat.com>

        * app/apptypes.h: add GradientPaintMode enum
        * app/paint_core.h: move above enum
        * app/paintbrush.c: use above enum

        * app/drawable_cmds.c: include "layers.h" so it
        will link again

	* tools/pdbgen/Makefile.am: Add apptypes.h.

	* tools/pdbgen/pdb/drawable.pdb
	* tools/pdbgen/pdb/layer.pdb: Add a few casts.

	* app/*.[ch]: Actually use the enum types GimpImageType,
	GimpImageBaseType, LayerModeEffects, PaintApplicationMode,
	BrushApplicationMode, GimpFillType and ConvertPaletteType, instead
	of just int or gint. Hopefully I catched most of the places
	where these should be used.

	Add an enum ConvolutionType, suffix the too general constants
	NORMAL, ABSOLUTE and NEGATIVE with _CONVOL. Use NORMAL_MODE
	instead of NORMAL in some places (this was what was intended). Fix
	some minor gccisms.

	* app/apptypes.h: New file. This file contains the above
	enumeration types, and some opaque struct typedefs. It was
	necessary to collect these in one header that doesn't include
	other headers, because when we started using the above mentioned
	types in the headers, all hell broke loose because of the
	spaghetti-like cross-inclusion mess between headers.

	(An example: Header A includes header B, which includes header C
	which includes A. B uses a type defined in A. This is not defined,
	because A hasn't defined it yet at the point where it includes B,
	and A included from B of course is skipped as we already are
	reading A.)

	* app/gimpbrushhose.c (gimp_brush_hose_load): Fix it. Now the hose
	itself, interpreted as a pixmap brush (which the hose is a
	subclass of), is the first brush in its list. The rest of the
	pixmap brushes in the list are separately allocated ones. Don't
	read the pattern names into dummy buffers, just seek past.

	* app/pixmapbrush.c (pixmapbrush_motion): Now works better, and
	actually steps through the pixmaps in the hose's list. The
	paint_core->brush (which points to a brush hose in the cases we're
	interested in) is temporarily replaced with the current pixmap
	brush to use, and restored after applying the pixmap brush.

	* app/makefile.{cygwin,msc}: Add new files.

Mon Aug 16 20:48:33 1999 Adrian Likins <alikins@redhat.com>

        * app/gimpbrushhose.c
        * app/gimpbrushhose.h: new files to implement a GimpBrushHose
        type. The idea being its derived from gimpbrushes, so we can
        make regular tools use it if need be, and fold it into the brushes
        dialog nice and easy.

        * app/gimpbrush.c
        * app/gimpbrushgenerated.c
        * app/gimpbrushpixmap.c:
        * app/gimpbrushpixmap.h: Modified the *_get_type() functions
        to behave more correctly. As suggested by Tim Janik <tim@gtk.org>

        * app/pixmapbrush.c: Since pixmapbrush tool wasnt doing anything
        useful anyway, start using it as a testbed for "image hoses".
        Right now it doesnt really work correctly.

I'll try to upload a sample hose to http://adrian.gimp.org/pixmap-brushes/
shortly, and maybe some docs about the lame format.

	* app/transform_core.c: Use RINT instead of rint.

	* plug-ins/common/curve_bend.c
	* plug-ins/sel2path/spline.c: Workarounds for gccisms, thanks to
	Hans Breuer.

	* app/makefile.msc
	* plug-ins/makefile.msc: Misc fixes.

	* app/transform_core.c: put the gimp_matrix_is_simple
	optimization back in.

	* app/transform_core.c: data access optomizations from
	David Hodson <hodsond@acm.org>

	* app/appenv.h: Add G_SQRT2.

	* app/iscissors.c: Use it.

	* app/makefile.{cygwin,msc}: Add new files.

	* */makefile.{cygwin,msc}: Use libintl extracted from glibc from a
	separate directory, not from gettext, because of licensing issues
	(we want to use the LGPL version in GTk+, so use it here, too).

* app/appenv.h: added a G_PI_2

* app/brush_header.h
* app/pattern_header.h: prefixed each FILE_VERSION with
G{BRUSH,PATTERN} to avoid namespace collision

* app/patterns.c: reflect above change

* app/iscissors.[ch]: merged in Austin's iscissors rewrite.. still
unfinished, but it's not like the old one did anything useful
anyway ;)

-Yosh

Other systems may eventually behave differently when it comes to atan(PI/2),
so please test this on other platforms...
