Summary: ALL: Enabling different aspect ratio correction methods
Initial Comment:
This patch makes it possible to switch between
different aspect ratio correction modes (which can be
useful e.g. if "exact" is too slow) with Ctrl-Alt-a.
I've updated both the SDL and OpenGL backends, but I
haven't given the latter much testing really.
In my highly unscientific tests, I concluded that
"sloppy" is alittle faster than "fast", "exact" is the
slowest by far, and I usually can't tell any difference
between the output of "fast" and "exact".
The patch is not quite backwards compatible with
current behaviour:
I've changed the --aspect-ratio command line option to
-r<mode>. This is partly because I can't be bothered to
write code to handle long options properly right now.
It should be noted that -r has been reserved as a no-op
for backwards compatibility since 0.2.0 or earlier. I
haven't checked what it used to do.
Putting "aspect_ratio=true" in .scummvmrc / scummvm.ini
no longer works since "true" is not a valid mode. This
could be a problem since ScummVM refuses to start if
there are this kind of errors in the config file.
