Hi,
I wrote a first version of a “SDL 1.2 to 1.3 Migration Guide” on the
SDL wiki:
http://wiki.libsdl.org/moin.cgi/MigrationGuide
Currently it mainly cover graphics, but also looks at events and
extensions.
What do you think? Comments? Suggestions? Flames? 
Cheers!–

You may include reference to this file as an example how to convert your
game to SDL 1.3 more-less painlessly:

Good point, I grouped migration strategies and mentioned that header:
http://wiki.libsdl.org/moin.cgi/MigrationGuide#Strategies
Copy below:
== Strategies ==
Here we discuss migration strategies for your code base.
Basic technique: here’s how to detect the current SDL version:
{{{
#if SDL_VERSION_ATLEAST(1,3,0)
/* SDL 1.3 code /
#else
/ SDL 1.2 code */
#endif
}}}
=== Rewrite ===
The most obvious one: drop SDL 1.2 and rewrite everything for 1.3.
=== Backward-compatibility ===
There are good chances that your current 1.2 code will directly compile under 1.3. Check {{{include/SDL_compat.h}}} and {{{SDL/src/SDL_compat.c}}} to get an idea.
Your code will probably run slower though; in particular there will be no hardware surfaces.
Compatibility is not 100% correct though; for instance {{{SDL_SetPalette}}} flags are currently ignored.
=== Forward-compatibility ===
You may want to support both libraries, for instance because SDL 1.2 is currently better supported on your platform, or better packaged in GNU/Linux distros.
The !AlienBlaster code, in the Android port repository, uses a few additional functions on top of SDL, that will use either SDL 1.2 or 1.3 seemlessly, and minimise the amount of #ifdef. It’s not completely fool-proof though, for instance blits between hardware surfaces will result in a no-op under 1.3. Check the C++ code at:
