Ensured Tux Paint's built-in help ("tuxpaint --help"),
Unix manual ("man page"), and command-line option
tab-completion list all cover the full set of Tux Paint
options. Some were missing in a few places.
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.
Using XDG's user dir settings to determine where pictures are
stored for a user (e.g., "~/Pictures" -- used as a fallback).
May be overridden using "--exportdir".
Also, while I was updating some docs, replace references to
"Mac OS X" with "macOS", the new name of that OS these days.
Ability to disable stereo panning effect (e.g., paint brush, UI
elements sound effect feedback, etc.), useful for users with
hearing impairment in one ear, or situations where one speaker or
headphone is being used. Use "--nostereo" command-line option
or "nostereo=yes" config. file option.
New option to place color palette items at the end of the "New"
dialog, rather than at the beginning. Useful for when users
would want to pick from a set of Starters and/or Templates,
e.g., in a school or museum environment.
Available via command-line option "--newcolorslast", and
config file setting "newcolorslast=yes". (And anti-option to
override config file settings, "--newcolorsfirst" and "...=no",
which represents the original behavior, which continues to be
the default).
Suggested by Bernard Verhaeghe.
* Added "--joystick-dev" option, for specifying which joystick device
Tux Paint should listen to
* "--joystick-dev list" is now used to list the available devices
* Cleaned up some 'usage' output
