- Introduce AtariSurface: a surface which represents either a
bitplane-based or pixel-based surface (on SuperVidel, as an inherited
SuperVidelSurface). Screen::surf / Screen::offsettedSurf are its
instances.
- Graphics::Surface::create / free now handle all Atari-related surfaces
via dlmalloc: ST RAM (TT/Falcon), VRAM (SuperVidel - 0xA0xxxxxx) and
VRAM for generic surfaces (SuperBlitter - 0xA1xxxxxx or ST/TT RAM).
This allowed me to remove all the hacky stuff from atari-graphics and
atari-superblitter.h.
- blit-atari.cpp now contains only blitting code
(SuperBlitter/move16/fallback), SV code is in
atari-supervidel.{cpp,h}.
- Take advantage of Common::ScopedPtr and Graphics::ManagedSurface's
dispose flag for Screen::surf as well Graphics::ManagedSurface's
ownership for Screen::offsettedSurf.
- Improve recoverability if an error/assert happens in
AtariGraphicsManager's c-tor/d-tor.
