Unlike "directional" brushes, in which a 3x3 grid representing the
8 cardinal directions (45 degree steps) is used, only a single brush
image is required, and Tux Paint will rotate it between 0 and 360 degrees,
depending on the direction the mouse is going.
The brush's ".dat" file should contain a line consisting of the word
"rotate".
Note: This adds a dependency on "SDL_gfx" library (Homepage:
https://www.ferzkopp.net/wordpress/2016/01/02/sdl_gfx-sdl2_gfx/
SourceForge project page: https://sourceforge.net/projects/sdlgfx/)
as this feature use it's "rotozoom" functionality.
WIP -- Doesn't handle animated brushes correctly yet!

Some already-translated (but very out-of-date) content
has been replaced with not-yet-translated (i.e., English) content.
Translators may want to look at the previous revisions of these
files when translating the new 'tuxpaint-docs' gettext catalog.
Sorry to cause extra work here, if I've done so.
About to drop in generated docs from the new 'tuxpaint-docs' repository.
As the directories will have more explicit names (e.g., "fr_FR.UTF-8"
rather than just "fr") and Spanish ("es") and French ("fr") already
exist (though they are very basic samples, 99+% untranslated so far),
renaming the current directories to match.
