- Private state screen information now hangs off the public one, instead of the other way around
- Combines video_global and video_private into a single structure
The following shook out from this that are applicable to other devices as well:
- running_machine is no longer taken, passed or stored
- mc6845_t is now private
- since passing device_config's is not device type safe, I added a
get_safe_token() to mc6845.c to check the device passed in for the valid type.
I think something like this should be added to the core.
- As a side note, I really don't think that device_config is a good name,
naming it simply device_t or something like that might be better.
than tokens and individual bits to the device callbacks. Updated
all existing devices accordingly.
Removed machine from the parameters of some of the device_get_info
and device_set_info calls because that information is stored
with the device now.
* Change "Machine->" to "machine->" in AM_BASE_MEMBER, AM_SIZE_MEMBER
* Pass Machine in construct_address_map
This is not perfect yet, but there is no need any longer to include deprecat.h in drivers using AM_*_MEMBER.

Hi.
In 0.123u3 the bug "multiscreeninfo0123u2gre" was fixed, however it changed
its behaviour as it now shows the "default" resolution the driver uses
rather than the resolution the screen(s) actually use at the moment.
As I don't know if this change was intentional I've attached a simple diff
that changes from defstate.visarea to the real visible visarea.

which specify device read/write handlers in address maps, along
with the type/tag of the device they reference.
Converted MC6845 read/write handlers to READ/WRITE8_DEVICE_HANDLERs.
Updated all MC6845-using drivers to use the new macros and call
the updated functions. Removed the many little helper functions
that used to do this work.
Added validity checks to ensure that the devices referenced
actually exist.
Updated all call-through handlers appropriately. Renamed read8_handler to
read8_machine_func, replicating this pattern throughout.
Defined new set of memory handler functions which are similar but which
pass a const device_config * in place of the running_machine *. These are
called read8_device_func, etc. Added macros READ8_DEVICE_HANDLER() for
specifying functions of this type. Note that some plumbing still needs to
happen in memory.c before this will work.
This check-in should remove the need for the global Machine and in turn
"deprecat.h" for a lot of drivers, but that work has not been done. On
the flip side, some new accesses to the global Machine were added in the
emu/ files. These should be addressed over time, but are smaller in
number than the references in the driver.
