Avoid STDERR messages on launch:
libpng warning: Interlace handling should be turned on when using png_read_image
(Except the fact that Tux Paint _itself_ saves drawings with
interlace enabled. :-/)
With this, closes https://sourceforge.net/p/tuxpaint/bugs/252/
Starting work towards

The ability to 'apply' a label to the canvas, making it permanent
(as if added using the "Text" tool instead).
Removed unused "label rotate" option's code (and hence addressed
a bug we didn't relalize when choosing the "Label" tool while in
in "--nostampcontrols" mode; the unused "rotate" button would appear).
Tweaks to icon. Further modularized how color button rendering works,
so it can handle selector (pipette) and mixer overlay icons.
Mixer function is basically identical to color picker (rainbow palette)
as a placeholder. WORK IN PROGRESS.
Also, modularize color picker's & color selector's method of
generating a fresh version of their active/inactive buttons,
after a color has been chosen by their tool.
On-screen keyboard (visible when the feature is enabled, while
using the "Text" and "Label" tools) now appears with larger
(48x48 pixel, vs 24x24 pixel) buttons, when Tux Paint's window
(or fullscreen) size is large enough to fit them with the
chosen layout.
(h/t Anat & Aviv, who suggested it to help with users of
eye-tracking systems)
Also, on-screen keyboard buttons use a slightly larger font
(16pt vs 12pt, previously seen on the small keyboard;
32pt on the large keyboard).
Adding control buttons to the Shapes tool, allowing for shapes
to be drawn from the center (as before) or from a corner
(more like other paint packages). The controls do nothing
at this time, but are visible and can be clicked. This is a
work in progress.
The controls may be removed using a configuration option.
From "Open" dialog, select an image (single click, or use
arrow keys / etc., to highlight the image), then select the
"Export" button at the lower right.
The image will be saved in the export directory. By default
this will be based on the config found via the XDG_CONFIG_HOME
environment variable, which is scanned for a "XDG_PICTURES_DIR"
setting. If none is found, "Pictures" in the directory specified
by the HOME env. var. will be used. In both cases, a new
"TuxPaint" subdirectory will be created, and exports will be placed
there.
The export location may be overridden using the "--exportdir"
command-line option or "exportdir" config file option
(e.g., "--exportdir /path/to/dir" or "exportdir=/path/to/dir",
respectively). In this case, the directory is assumed to preexist,
and no "TuxPaint" subdirectory will be made.
There's currently no way to disable the export feature altogether.
If there's demand, we can add it as a simplification option.
Finally, this feature simply copies the PNG file (but no extra
data files) from Tux Paint's "saved" directory to the export dir.
Closes https://sourceforge.net/p/tuxpaint/feature-requests/192/
Beginning addition of an option to export animated GIFs
from the Open -> Slideshow dialog, after choosing the images.
Non-operable at this time, but a button has been added (and will
provide a hint to select 2 or more images, when clicked).
Replace the somewhat-recently-added "nothing" item in the tool bar
with the "Fill" tool, which has been converted back from a Magic tool
to a regular tool.
Also, change bash "==" to sh "=" in "if [ ... ]" tests in Makefile.
Also, link to math library (via "-lm") to make sure "max()" is available to
magic tools.
Also, add missing mention of "--newcolorslast" and "--newcolorsfirst" to manpage.
from over 50,000 colors. Used by drawing and Magic tools, as well
as the new 'New' dialog.
Documented Martin's Mac OS X printing update.
Improved colors in Starter browser buttons.
Created Mirror and Flip Magic tools as plugins (except sound); hooks
added to Magic plugin API to allow starter and starter-undo mirror/flip.
Created Fade and Darken Magic tools as plugins.
Moved magic tool sounds to 'magic'.
Added flip and mirror icons to main Tux Paint UI (used to share magic tools')
Created 'tp-magic-config.sh' to get CFLAGS for compiling magic tool plugins.
Improved magic tool plugin API.
Committed some documentation on magic tool plugin API.
(Select each image to play, in the order you want them, then click "Play".
Space, Enter, Right and mouseclicks advance manually.
Left goes to the previous image. Escape or "Back" button at lower right ends
playback.)
