round() is C99; floor() and adding 0.5 to the parameter is sufficient. Probably having detection for floor() and a compatibility definition otherwise would make sense.
This fixes a bug where the player could be stuck on Channelwood's
lower level with the elevator on the upper level.
This also turns the light off on Stoneship when entering the age,
since the battery is depleted.
Thanks to dtungsten for submitting this fix in PR#478.
Each engine now only has to provide a single configure.engine file
adding the engine into the configure script, which then produces the
required other files automatically.
This is the third and final commit enabling fully pluggable engines.
Now providing an engine folder contains a configure.engine, engine.mk
and engine-plugin.h file, it will be picked up automatically by the
configure script.
This is the second part of allowing engines to be added dynamically.
Each folder in engines/ which must contain a file named "engine.mk"
containing the make definitions for that engine.
This is the first part of allowing engines to be added dynamically.
They are placed into a folder in engines/ which must contain a file
named "configure.engine" to add the engine, which is pulled into the
top level configure script automatically.
Otherwise there may be both a book video and a flyby video playing
at the same time. Maybe it should only stop videos if there really
is a flyby video, but it already stops all sounds and may play a
blocking sound etc., so it makes sense to me to always do it.
Clicking on any of the image boxes would fall through to the case
where it checks if you are picking up or putting away the white
page, which just doesn't make any sense. It didn't have any
noticeable impact on the game, because that case only does
something if the hiding place for the white page is open, and
apparently that can only happen while you're at that hiding place.
I have verified that it's still possible to get the white page,
and that it's still possible to raise the sunken ship.
This allows to keep the engines to specfiy the files for translation close to
the engine sources itself.
Thanks to criezy for his suggestion on this approach.
