The original also had a cool sphere showing stick-line constellations,
but it wasn't ever shown. This fixes the display and adds c as a
toggle for it when viewing the starmap
The original had a pretty cool patchwork boundary area sphere
display option for the starmap puzzle, but didn't actually hook
it up. I've now bound it to the B key, and fixed bugs in it's display
The original actually freed the parser entirely from within findFrames,
and then recreated it each time a sentence is parsed. Since this is
nasty, and in ScummVM _parser isn't dynamically created, I settled on
adding a clear command to completely clear the parser instead.
This was a miss in commit 00e59a3122. The new parameter was supposed
to be called skipThumbnail and default to true instead.
For consistency's sake (the rest of the tree uses skipThumbnail, not
loadThumbnail) I'm reverting this and will separately update the
declaration to how it should have been from the beginning.
Thanks dreammaster!
This commit introduces the following changes:
1. Graphics::loadThumbnail()
Now returns a boolean and takes a new argument skipThumbnail which
defaults to false. In case of true, loadThumbnail() reads past the
thumbnail data in the input stream instead of actually loading the
thumbnail. This simplifies savegame handling where, up until now,
many engines always read the whole savegame metadata (including
the thumbnail) and then threw away the thumbnail when not needed
(which is in almost all cases, the most common exception being
MetaEngine::querySaveMetaInfos() which is responsible for loading
savegame metadata for displaying it in the GUI launcher.
2. readSavegameHeader()
Engines which already implement such a method (name varies) now take
a new argument skipThumbnail (default: true) which is passed
through to loadThumbnail(). This means that the default case for
readSavegameHeader() is now _not_ loading the thumbnail from a
savegame and just reading past it. In those cases, e.g.
querySaveMetaInfos(), where we actually are interested in loading
the thumbnail readSavegameHeader() needs to explicitely be called
with skipThumbnail == false.
Engines whose readSavegameHeader() (name varies) already takes an
argument loadThumbnail have been adapted to have a similar
prototype and semantics.
I.e. readSaveHeader(in, loadThumbnail, header) now is
readSaveHeader(in, header, skipThumbnail).
3. Error handling
Engines which previously did not check the return value of
readSavegameHeader() (name varies) now do so ensuring that possibly
broken savegames (be it a broken thumbnail or something else) don't
make it into the GUI launcher list in the first place.
