Previously the file format had all chunks, offsets and values stored in
little-endian format. The one exception was screenshots, which used the
existing THMB code in graphics/thumbnail.cpp, that is entirely
big-endian. Any tooling which attempts to parse the Event Recorder file
format must make a special exception for THMB chunks, and read the chunk
size and contents as big-endian.
In the interests of making the file format more consistant
to parse, and given that backwards compatibility is not required for
this iteration of Event Recorder, this patch changes everything to
big-endian.
Screen update boundaries are now used as sync points.
Screenshots are now processed on a screen update boundary.
This change increments the version of the Event Recorder
file format to 2; version 1 files will still play back as
before, without synchronising to screen updates.
This might also become a return to launcher, but I've somehere read the hint that
the event recorder was only meant to play back one game per session. We'll see.
