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.
simulate_flood_fill_outside_check() could spin in an
infinite loop because it could sometimes set values in the
`touched[]` array to 0, which means the spot was never seen.
Values going in there are not boolean, but a 0-255 gradient,
for smoother fills on antialiased edges.
This change forces it to be a 1-255 value, ensuring that
a 'touched' spot on the canvas will have a non-zero `touched[]`
value.
h/t Pere for noticing the bug, providing some details,
and best of all providing a sample image to play with which
consistently invoked the crash. (It made mending this a
10 minute task for me, rather than an hours-long hunt to reproduce!
Big 'thanks' for doing that ahead of time!!!)
Known Issues
------------
- No printing support.
- No typing support using the OS virtual keyboard. iOS needs to be signalled
to bring up the virtual keyboard when the text tool is active. We also may
need to do some finagling to make IM work with the virtual keyboard.
- OS language detection doesn't work yet.
- Quitting doesn't close the app. It just displays a black screen until it is
force-closed.
- Need to include cross-compilation instructions.
Possible Issues
---------------
- No text display. This is likely an issue with how pango and related
libraries were cross-compiled rather than an issue with Tux Paint code. From
the error output it appears to be a font rendering issue.
- SVG integration couldn't be tested because RSVG library has not yet be
cross-compiled successfully.
- Only tested under the iOS Simulator (and not on an actual iOS device yet.)
