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).
(h/t Jackson Bray for the suggestion)
Also, slight improvements to how circular eraser size calculations
are handled, to allow for radius down to ERASER_MIN of 5.
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.
See "RELEASE.txt" for the invocation. Mended a few things prior
to final run of `tidy`, based on HTML Tidy's output.
Updated any affected TXT files via Makefile.
Planning to run 'tidy' on the HTML doc files. Documenting the
arguments I'm providing to 'tidy', for future reference,
within the RELEASE.txt file.
Also, cleaned up and improved RELEASE.txt.
Tux Paint can export an animated GIF to the export directory
(e.g., ~/Pictures/TuxPaint) from the Open->Slideshow dialog.
To do -- GIF's animated speed should be based on speed slider
in Slideshow dialog.
To do -- Document this new feature (and single image (PNG) export)
in the README documentation.
i18n code was checking for local-related environment variables
(e.g., "getenv("LANGUAGE")") coming back as a NULL if unset.
However, on my laptop, under Kubuntu 20.04 with GLIBC 2.31, a
"LANGUAGE" env. var. is set, but it's blank.
Tux Paint failed to attempt any fallback (e.g., checking "LANG")
in that situation, which was causing the description text corruption
that was corrected in a previous commit.
That commit also mistakenly suggested that the issue might've been a
difference with GCC versions, but the problem was deeper in Tux Paint's
code (in i18n.c), and was triggered by an unexpected environment.
