Subject: twin16 update
Hello,

Attached is an update for the Konami twin16 driver, see diff for details.
Functional changes:
- improved sprite status register, this fixed the rogue sprites problem in devilw
- added fround coin counters
- lowered k007232 volume
- added savestate support
- added shadows
- fixed devilw and gradius2 sprite lag
- added text layer x/y flipping
- reverted gradius2 sprite-background priority hack, this fixes severe priority problems in 
devilw, but reintroduces bugs on gradius2 level 7 and ending

affected mametesters bugs:
fixed: 02267, 00191, 02553
partial, due to revert: 02523 (intro is ok again, but old priority bugs are reintroduced), 
02268 (ok in-game, small priority problem in prologue)

Greets,
hap

TODO: TODO:
- convert background to tilemap - convert background to tilemap
- clean up sprite drawing - clean up sprite system
- sprite-background priorities - bad sprites in devilw, eg. odd colours for the mud/lava monster in the 1st level,
- sprite lag in devilw or wrong sprite-sprite priority sometimes -- check real arcade first
- sprite Y axis lag in vulcan - unsure about some sprite preprocessor attributes (see twin16_spriteram_process)
- add shadow sprites (alpha blending) to sprites in at least devilw

sprite-background priority: in devilw, most sprites look best at high priority,

- devilw prologue: sprites should be behind crowd
- gradius2 level 7: bosses should be behind portal (ok except brain boss and mouth boss)
- gradius2 ending: sun should be behind planet
does TWIN16_PLANE_ORDER affect it?
more?
devilw monster dens exploding monochrome, players fading to white in prologue, and trees in
the 1st level shrinking with a solid green color look odd, maybe alpha blended?
