Was failing to compile on Haiku for Luc (apparently building with
no SVG support), since I started using that function outside of
SVG-related places.
Also, to continue being able to compile on Linux with no SVG support --
* Always use SDL_TRUE & SDL_FALSE, not TRUE & FALSE
* Always link tuxpaint with "-lm"
Finally, verbose version info ("tuxpaint --verbose-version") now states which
SVG build (new RSVG or old Cairo)
I noticed that buttonsize=90 or =91 would end up with UI buttons
images ere one pixel smaller (89x89 or 90x90, respectively) than
expected, hence they layout would end up with one row and one
column of unused pixels between them. Any button content (e.g.
stamp thumbnails) that might render into the full size would end
up leaving garbage pixels behind.
Applying ceil() to the new_x and new_y (but then making sure they do
not exceed the requested max_x and max_y) calculated sizes inside the
thumbnail2() function. (We do not simply use max_x and max_y directly,
because we are usually trying to maintain the original image's aspect
ratio.)
Was redrawing color toolbar _before_ changing the chosen color
to be the pipette tool.
Reproducing the bug - Select a built-in color, Ctrl+click in the canvas,
observe built-in color still appears chosen [the bug], paint with e.g.,
paint brush, observe it's using the correct, pipette-selected color,
not the one that appears chosen [this is correct].
If `convert` fails, and didn't generate a file at all, `make` would
abort due to `rm` being unable to delete the non-existent broken
thumbnail. Using `rm -f` now, so it doesn't abort if the thumbnail
file didn't get created AT ALL.

Motivation - Without SDL2_Pango, languages like Japanese,
Arabic, and Thai do not render properly. Currently, Debian
(and hence Ubuntu) do not have SDL2_Pango, so Tux Paint 0.9.28
is adversely affected. Fedora DOES have SDL2_Pango, so works well.
This also allows us to delete a lot of ancient cruft code.

(INSTALL docs to be updated momentarily)
This seems to allow me to specify which display (monitor) to make
Tux Paint appear on my two-monitor set-up (laptop + external monitor)!
Closes https://sourceforge.net/p/tuxpaint/bugs/277/
