I tried to cover most of the things that seem to be interesting
for the end user. I excluded the SCI32 stuff because a) it's not
officially supported and b) I don't have the slightest clue what
most of the changes to the SCI32 engine do. :)
Please excuse if you made a noteworthy contribution I missed
to mention in this NEWS update. It was not on purpose.
Some games load palettes that include color 255, but this is
hardcoded to white in SSCI, so just ignore it during merges since
it is ignored when the hardware palette is updated anyway.
Avoid forcing the screen to refresh after a palette change if the
screen is also about to be drawn to, as the palette change + draw
is intended to be an atomic operation.
Changes theme stx files to specify TabWidget's type. That fixes wrong TabWidget height.
Changes TabWidget's getHeight() to return not only "children" height, but also tabs height. That fixes wrong clipping area.
Changes Widget's findWidget to use getHeight(). That fixes bug when widgets in the bottom of TabWidget were not reacting to the mouse events.
Subtitle box should now always use color 255, which should be
white all the time. Normally it uses color 7, which is white
most of the time, but for example pink/purple at the start of
chapter 5.
With the addition of the transparent pic type code, the _type
property would be read uninitialised by setType if _pictureId was
set to kPlanePic.
CID 1357230, 1357231.
Sometimes, games accidentally use palette entries that are not
marked as used and expect them to be a particular colour, like the
Phantasmagoria title screen, or the white palette entry (always
255 in DOS/Win).
Several functions in Audio32 would call into the mixer to pause
or resume the audio handle, which would cause a deadlock if the
mixer's mixCallback timer fired while one of these functions was
running on the main thread.
To address this, calls to mixer to pause/unpause the digital audio
handle have been removed. Since this was just an optimisation to
prevent unnecessary calls to fill the audio buffer, the only
problem now is that a tiny amount of CPU is wasted on unnecessary
callbacks to read from the empty SCI mixer.
