h/t Pere for adding the missing pieces.
WIP b/c there's one minor side effect that needs addressing
(final label, highlighted red, does not lose its highlight)
Onscreen keyboard repositions itself to the top if you use [Enter]
to move the cursor down, and it begins overlapping the keyboard.
Also, play "carriage return" sound effect, even when entering
a blank 'line' of text.
Catching up with latest devel
Still things to solve/do:
Apply label seems to not work, neither in master
Onscreen keyboard size doesn't perform as in master
Test on other OSs, Windows, Android, ...
Fixed the issue with the backspace not working in text and label tools
when in certain language modes in macOS. Mac keyboards have the DELETE
key where PC keyboards have the BACKSPACE key, and the two keys have
different keycodes, so the backspace requires special handling on the
macOS in programs writtens for the PC.
Avoid leaking memory when loading Label text strings from a saved drawing.
Also, a heck of a lot of comments to explain (as best I understand)
what load_info_about_label_surface() is doing.
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.
A keyboard shortcut is now available for picking colors from
the canvas more quickly. Hold either (left or right) [Ctrl] key
while clicking, and the color selector option will appear.
Release the mouse button over a color on the canvas to choose it
(or outside the canvas to abort).
Closes https://sourceforge.net/p/tuxpaint/feature-requests/209/
Also,
* Don't play 'bubble' paint sound when color picker or selector
are aborted (e.g., via their "Back" buttons).
* Replace many instances of "NUM_COLOR - 1" and "NUM_COLOR - 2"
(which correspond to color chose via picker (palette) and
selector (canvas), respectively) with #define's that
represent them. (Avoid magic numbers.)
