This will only log things going through dynapi, which means it won't
do anything if dynapi is disabled for a given build, but also things
that call the `*_REAL` version of an API won't log either (which is
to say, if an internal piece of SDL calls a public API, it won't log
it, but if an application calls that same entry point, it will).
Since this just inserts a different function pointer, unless you
explicitly request this at runtime, it won't add any overhead, and,
of course, the entire thing can be turned off with a single #define
so it doesn't even add extra unused code to the shared library if
the kill switch is flipped.
Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.
