* 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).

(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? :-)

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.

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

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.

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).

mode), but you have to set the scaling UV registers in order to have correct
overlay.
* In other words, overlay is working now! There are still issues with it, which
can probably be attributed to missing bounds checks (the screen goes black
when you leave full-screen mode in VLC - but not if overlay just stops).

the Intel chip obviously cannot do overlays in B_RGB16 - even though it pretends
to be able to do that.
* B_YCbCr422 seems to work, though, I haven't tested any other spaces for now, and
I somewhat doubt they will work. It's all green, though, and the scaling doesn't
seem to be correct - that we be solvable, though :)
* There aren't any bounds checks (so don't move the window out of the screen), and
also the overlay_view offsets are ignored.
* Scaling and moving is now detected, and there is always as little work done as
possible to reduce the workload on buffer switches (the most common case).

lsb to msb).
* The result is that there is now *something* to see when overlay is turned on. In
fact the whole screen goes dark besides a few pixels on the top - now isn't that
something? :-)
* The overlay is also turned off again correctly - which also revealed a bug in our
app_server: B_CONFIGURE_OVERLAY is not always called with window=NULL/view=NULL
to turn off overlay (might be an incorrect handling of BView::ClearOverlay()).

small) up for this specific task - this will later be used for the acceleration
engine as well.
Some more work on overlay initialization, doesn't do anything yet, though.

to be used.

* Changed driver name to start with "intel_extreme" to have a nicer device
name.
* Renamed frame_buffer* stuff to graphics_memory* as the frame buffer just
happens to be located somewhere in the graphics memory.

* Some preparations to support more than one chipset, added i855G (device ID 0x3582)
to test with - the accelerant_device_info is now filled with that additional data
as well.
* Some minor cleanup.

Only mode switches do work, doesn't yet make sure the mode is valid, though.
At this point, this driver only works on Haiku, the R5 app_server is crashing for some
reason I need to investigate some day (maybe tomorrow :)).
