It looks like the _videoMode.overlayHeight in SurfaceSdlGraphicsManager::grabOverlay and ThemeEngine::_backBuffer::h are somehow out of sync after
starting the game in a different resolution as the gui was started with. So the overlayHeight is updated - but the backbuffer (Surface) is not resized.
This is with event recorder being active - right after starting the game and switching the resolution.
By letting the user select which group of plugins to load, an out of
memory condition can be avoided while still allowing all plugins to be
stored on the same disc.
Engines should only have to call one set of functions and not decide between the two. In fact, the 'emulation' API was documented to just call the 'real CD' API.
This removes the need to convert the parameter to copyRectToScreen to
"const byte *", which is commonly used in games, which use Graphics::Surface
to store their graphics data.
All uses of the old target scale API actually wanted to disallow scaling of
the mouse cursor. This commit adapts our API to this and thus simplifies
backend implementations.
Some backends, most notable the Wii and Android, did some implementation of
the cursor target scale, which I didn't adapt yet. I added a TODO for the
porters there.
Implement platform-specific variants of createConfigReadStream()
and createConfigWriteStream(), instead of inheriting the BaseBackend
definitions. Nonstandard behavious is as follows:
* createConfigWriteStream() always returns 0 (read-only filesystem)
* createConfigReadStream() returns an empty MemoryReadStream instead
of NULL if scummvm.ini does not exist. This is to make sure that
loadDefaultConfigFile() always clears out any old config data, as
I'll want to restart config parsing from scratch after a disc
swap.
