[AL] extrange thing noticed on Allegro Windows (3.9.33)

[<xav...@ho...>]

Hello everybody,
I have noticed a extrange maybe? thing...
this is, when using DIRECT_X and AMNESIA it says its supported... ok
when using DIRECT_X and PAUSE it says its unsupported... ok too
now
when using DIRECTX_WIN and AMENSIA it says its supported BUT
the program still runs even without the focus
AND when using DIRECTX_WIN and PAUSE it says its SUPPORTED and
now the program doesnt run when not focused

is all this normal?

thanks!

Yes, the switching mode policy isn't the same in fullscreen mode as in windowed
mode:
- in fullscreen mode: only SWITCH_AMNESIA and SWITCH_BACKAMNESIA are supported
because Allegro isn't able to remember the contents of the video memory.
- in windowed mode: only SWITCH_PAUSE and SWITCH_BACKGROUND are supported, this
time because Allegro do remember the contents of the screen. But this applies
when the color depth of Allegro's screen and the color depth of Windows' desktop
match. If they don't, you can't switch your application into the background with
the 3.9.33 code; with the new 3.9.34 code, you can *but* then only SWITCH_PAUSE
is allowed.
Ultimately, you have to check the return value of set_display_switch_mode().
