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!

Always show the appropriate instructions at the bottom when the
"Fill" (depends on which sub-tool chosen) and "Shapes" (depends
on whether "simpleshapes" option is set) tools are selected
(e.g., when returning from the "Open" dialog).

The Makefile variable "HOST" was introduced to cross-compile Tux Paint
for iOS. Unfortunately this variable is often set at the environment
variable level on many Linux distributions so it can cause the Makefile
to think it is attempting to be cross-compiled when that is not the
intention.
This change modifies the Makefile so it attempts to cross compile only
when both HOST and HOSTROOT environment variable (which are both
required for cross compilation) are set.
Just a bit of the beginning of "tuxpaint.1" has been
wrapped in localizing "gettext()" calls. Generating
snapshot of new English version, as well as Spanish,
French, Galician, and Japanese, based on the PO files
that exist over in `tuxpaint-docs` repo.
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.
