2011-03-24QUEEN: Rename some MidiMusic members to match Audio::MidiPlayerMax Horn
2011-03-23ENGINES: Further simplify pseudo MidiDrivers; fix some regressionsMax Horn
The regression affected AGOS and maybe some others; specifically, the real MidiDriver would have been deleted twice -- I previously missed that the Engine instances takes care of freeing the real MidiDriver, not the MidiPlayer wrapping it. This commit should clarify the ownership of the real MidiDriver for most pseudo MidiDrivers.
2011-03-23AUDIO: Change several fake MidiDrivers to MidiDriver_BASE subclassesMax Horn
Many engines follow the advice in audio/midiparser.h and create a "pseudo-MidiDriver" subclass. But MidiParser really only needs a tiny subset of the MidiDriver capabilities, namely those found in MidiDriver_BASE. So we try to subclass from that whenever possible; this allows us to remove many stub methods, and enables further future simplifications.
2011-03-22AUDIO: Add pure virtual MidiDriver::isOpen() methodMax Horn
This in turn enables modifying MidiDriver_MPU401::close() to allow it to be called on a midi driver that has not yet been opened. The specific issue that triggered me to make these changes was a crash-upon-quit in HUGO, caused by it instantiating a midi driver, then encountering an error (missing hugo.dat) *before* having opened the new midi driver; the general cleanup code then tries to close the (not yet opened) midi driver -> kaboom Also fixed some engines which were leaking MidiDriver instances.
