WIP Rotational brushes now supported

Browse source 
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.

Pinceaux animés orientables
Rotating Brushes
Vous pouvez mélanger animation et orientation dans un même pinceau.
Utilisez les deux options ("frames=N" et "directional") en deux
lignes séparées dans le fichier ".dat" qui concerne le pinceau.
As of Tux Paint version 0.9.27, you may now create rotating brushes.
As the brush is used, it is rotated 360 degrees, depending on the
direction the brush is going.
Disposez le pinceau de manière à ce que chaque ensemble 3x3 de
formes orientables soit disposé sur une grande image PNG. Par
exemple, si le pinceau mesure 30x30 et qu'il y a 5 cadres, ce sera
450x90. (Les 150x90 pixels les plus à gauche de l'image représentent
les 9 formes de direction pour la première image, par exemple).

Animated Directional or Rotating Brushes
You may mix both animated and either directional or rotating
features into one brush. Use both options desired ("frames=N" and
"directional" or "rotate"), in separate lines in the brush's ".dat"
file.
For directional brushes, lay the brush out so that each 3x3 set of
directional shapes are laid out across a wide PNG image. For
example, if the brush is 30x30 and there are 5 frames, it would be
450x90. (The leftmost 150x90 pixels of the image represent the 9
direction shapes for the first frame, for example.)
Placez les PNG de l'image du pinceau (et tous les fichiers texte de
données) dans le répertoire "brushes".
