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.
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.
find -name '*.h' -or -name '*.cpp' | xargs sed -r -i 's@\(([A-Za-z0-9]+)\*\)@(\1 *)@g'
This seems to have caught some params as well which is not undesirable IMO.
It also caught some strings containing this which is undesirable so I
excluded them manually. (engines/sci/engine/kernel_tables.h)
- Update BaseBackend and DC port to properly implement OSystem::fillScreen (now only PalmOS has to be updated).
- Update all client code which relied on OSystem::clearScreen so far.

Fixed alpha blending in the UI dialogs by adding alpha
computation to the blendPixelPtr() function. To minimize
impact, pre-multiplied alpha is assumed, meaning that the
blending of the R, G and B components is the same both
with and without hardware alpha.
