* Rotating brush angle is now a double, not an int
* Don't draw once on click; require some motion
(does not affect directional brushes, which include
a "no movement" shape in the middle of the brush bitmap)
Following warnings still remain so far.

When assembling UTF-8 in render_text_w() (to send to SDL_Pango),
we assumed `wchar_t` could encompass the entirety of Unicode
(up to U+10FFFF); however, on Windows `wchar_t` is only 16-bits,
meaning the test for characters <= U+FFFF was always true.
This reworks the if/elseif/else block, via some "#ifndef WIN32"
tests, to avoid this warning.
In the end, we need to replace our internal use of `wchar_t`
with something 32-bit, to allow for higher Unicode code points
(e.g., to support Emoji via the Text and Label tools).
Additonally, some work will need to be done to ensure that
text stored as Labels within saved Tux Paint images (PNGs) continued
to work correctly, and could be traded between platforms.
(Untested, but right now I assume a picture drawn on Linux where
`wchar_t` is 32-bit would break if you attempt to load it on Windows,
and possibly vice-versa?)
See https://sourceforge.net/p/tuxpaint/feature-requests/210/
Every version after when onscreen-keyboard implimented has this bug,
which first became apparent in Windows 10. (Because of more strict
memory handling or something?)
Recommend every windows user to upgrade to 0.9.26-5.
Was blindly calling thumbnail() on what came back
(which would be NULL if the image failed to load).
Also, mend bug where magic group arrays were being cleared
at the same time as stamp group ones; the latter is larger.
