I mended most of them.  There are two classes of warnings
which appear multiple times each, but I _believe_ I got
everything else covered.

I came up with some tricks to make sure all of the changes
were done in SDL-agnostic ways.  (i.e., the code is identical
in the SDL 1.2 (master) and SDL 2.0 branches, despite major
differences under those versions' hoods.)

These are the two types of warnings that still linger:

 * ‘rsvg_handle_close’ is deprecated: Use
   'rsvg_handle_read_stream_sync' instead

 * passing argument 3 of ‘autoscale_copy_smear_free’ from incompatible
   pointer type (SDL_BlitSurface)


One problem for me is that I can't get SDL2_Pango working.
I'm on Ubuntu, and tried installing the .deb packages from
Pere's SF.net project page (admittedly old, these days).

When doing so, I get a "pre-dependency problem":

  libsdl2-pango1 pre-depends on multiarch-support
  multiarch-support is not installed.

I'm not sure how to address that.


And when I try to compile the source .tar.gz, I also run
into trouble:

  kendrick@gambit:~/tuxpaint/SDL2_Pango-0.1.2$ ./configure 
  checking whether to enable maintainer-specific portions of Makefiles... no
  checking build system type... x86_64-unknown-linux-gnu
  checking host system type... x86_64-unknown-linux-gnu
  checking target system type... x86_64-unknown-linux-gnu
  checking for a BSD-compatible install... /usr/bin/install -c
  [...]
  checking that generated files are newer than configure... done
  configure: creating ./config.status
  config.status: error: cannot find input file: `Makefile.in'

It's been a LONG time since I installed anything with autoconf,
so I'm stumped.  (Googling lands all sorts of different answers,a
and often project-specific.  Ugh.)


I'd like to make sure the SDL2_Pango stuff works.

Under SDL 1.2 ("master") branch, when I build I get SDL_Pango:

  kendrick@gambit:~/tuxpaint/tuxpaint$ ldd ./tuxpaint|grep -i pango
          libSDL_Pango.so.1 => /lib/x86_64-linux-gnu/libSDL_Pango.so.1 (0x00007f0cd3472000)
          libpangoft2-1.0.so.0 => /lib/x86_64-linux-gnu/libpangoft2-1.0.so.0 (0x00007f0cd1ce1000)
          libpango-1.0.so.0 => /lib/x86_64-linux-gnu/libpango-1.0.so.0 (0x00007f0cd1c92000)
          libpangocairo-1.0.so.0 => /lib/x86_64-linux-gnu/libpangocairo-1.0.so.0 (0x00007f0cd177a000)

...but, obviously, under SDL 2.0, I don't get SDL2_Pango: :-(

  kendrick@gambit:~/tuxpaint/tuxpaint$ ldd ./tuxpaint|grep -i pango
          libpangocairo-1.0.so.0 => /lib/x86_64-linux-gnu/libpangocairo-1.0.so.0 (0x00007f12a3ac6000)
          libpango-1.0.so.0 => /lib/x86_64-linux-gnu/libpango-1.0.so.0 (0x00007f12a3a77000)
          libpangoft2-1.0.so.0 => /lib/x86_64-linux-gnu/libpangoft2-1.0.so.0 (0x00007f12a2ac6000)

Thanks in advance!
