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.

Recently we started to use this as new semantics, although in the past
we used simly <engine>_H. Now these guard defines are consistent with
rest of the files which are used in the engines.

Some translated resources in Russian versions have incorrect unpacked
resource sizes. The original didn't perform checks for these, but we
do, thus we'll need to patch the unpacked resource sizes for each case

If the specificed savegame doesn't exist, start the game from the
beginning. Before, it would just hang. The error handling is still
quite primitive, though.

|
|
|
|
- Rename stuff

Sounds and music play now in some scenes
(I didn't change the comments to code in all modules yet)
- Fix calcHash to ignore non-alphanumeric characters, this fixes at least
one animation glitch (when inserting tapes into the player)
- Move SoundResource to sound.cpp
|
|
important code doesn't exist yet
|
|
- Started replace message numbers with constants
- Add NRect::contains
- Some cleanup
|
|
- Give better names to animation callback functions/vars
- Give better names to animation functions (previously known as subXXXX - not completed yet)
- Add dumpAllResources (which is a lie, since it only dumps animations for now)
- More renaming to come
|
|
- Implement Screen::drawSurface3 and Screen::drawUnk and move actual blitting code to Screen::blit
|
|
- Move GameModule::startup call into engine instead of the game module constructor
- Reduce debug output
|
|
- Work on the SmackerDecoder, create the surface immediately when a file is opened

later) and AnimResource related stuff
|
|
|
|
|
|
- Add dummies for game variable access
|
|
- Move common headers used in modules to module.h so they don't have to be explicitly #included in each module header
- Clean up #includes
|
|
- Implement Scene1501 (with yet unimpelemented stuff commented out)
- Add preliminary main loop to test stuff/updates
- Add dummy SoundResource
- And fix a mean bug/typo in some initializer lists...
(The intro now "runs" but doesn't show anything yet since the actual display code and other classes are not yet implemented yet.)
