TODO:
|
|
Right now our charset renderers directly access _textSurface, as well as the
|
|
virtual screens of ScummEngine. Ideally, this would not be the case. Instead,
|
|
ScummVM would simply pass the appropriate Surface to the resp. methods.
|
|
Of course it is not quite as simple, various flags and offsets have to
|
|
be taken into account for that.
|
|
|
|
The advantage will be cleaner coder (easier to debug, in particular), and a
|
|
better separation of the various modules.
