introduced a lock that is used in B_SET_DISPLAY_MODE etc.
* Correctly implemented B_ACQUIRE_ENGINE and B_RELEASE_ENGINE now (ie. they lock
the engine now).
* The lock of the ring buffers is now deleted when the (primary) accelerant is closed.
* Minor cleanup.

* Turns out cursor handling is simpler as originally thought, so I could remove its
physical mapping - it's still put into the shared area, though, although that isn't
needed for this chip (but could eventually simplify the handling of other generations
of this chip).

a settings file. However, you cannot specify less than the amount taken by
the BIOS (ie. your settings will be ignored if you do).
Just put something like the following into a "intel_extreme" settings file:
graphics_memory_size 16
To allocate 16 MB in total. Note, whatever value you specify will be rounded
up to the next power of two, ie. if you specify 6 MB, 8 will be taken.

(in the kernel driver) fail - or crash the system.
* Waiting for VBLANK now works as expected - you actually have to *set* the bit
to clear it, isn't that obvious? :-)

should help on bug #583, and even fix it
minor change in localtime

is no good (or reliable) way to retrieve the physical address of "stolen"
(by the BIOS) graphics memory.
* Implemented allocation of additional graphics memory in case the BIOS was
a bit too cheap. We now guarantee 8 MB of memory available to the graphics
chip - would be nicer to only allocate that on demand, though.

this is what bash is currently using (we're supposed to be posix compatible after all)
success on R5, R5 setjmp.h; fail on R5, Haiku setjmp.h (could be expected)
to be tested: on Haiku, R5 & Haiku setjmp.h

I am also not sure if it's working correctly.
* Minor cleanup.

this is mostly done because of the fact that I haven't tested how full it usually
is, and since I haven't implemented checking for free space yet...

use it (which isn't really that bad).
* B_SCREEN_TO_SCREEN_BLIT is now working as intended, so we can finally move
windows and scroll at decent speed :-)
* Implemented a simple version of B_WAIT_ENGINE_IDLE for now.

turned off - note also, that only the 32 bit mode is currently hardware accelerated!

be used to feed the ring buffers with new commands. It takes care about proper
alignment (this shouldn't be necessary in the final version, anymore, though), and
locking.

the usual order of other registers, so I mixed it up: vertical downscaling
is now working as expected as well.
* The downscaling factor was a tiny bit too low (one pixel from the view).

used, though.
* Renamed the PhyisicalPageMapper class to AreaKeeper and made it a bit more
generic (ie. it can now also create usual areas)
* The shared_info is now created using the AreaKeeper, too, and this actually
fixes some potential memory leaks.

overlay - this will improve the overlay performance when the engine is
under load (the acceleration engine will use the primary lower priority
ring buffer).
