We now keep track of a lower bound as to when the list should scale
itself back down. When increasing the list size, we double the current,
with the lower bound set to 1/4 of the current size, not allowing it to
go any smaller than the block size. These combined allow us to do very
cheap tests to see if an operation requires a resize at all, and minimize
how often the list actually needs to be resized, since the difference in upper
and lower bounds prevents bouncing back and forth between a size in the case
of adding/removing an item while close to a boundary. All in all this should
make BList noticably more scalable when doing large numbers of add/remove
operations.

When changing to icon mode with a size other than 32 (ie: kScaleIconMode) PoseView calls Refresh() and all the poses are
removed and loaded again (PoseView.cpp line 1995). This called AddPoses but didn't check for ShowDiskIcon(). The Disks icon
was shown on startup though, since Tracker uses another code path when starting (caching?).
This fixes#1833.

the delta.
For example, MoveBy(-0.5, 0.0) would do nothing in this case:
roundf(150.0 - 0.5) = 150.0, when rounding the delta it gives the
expected value: roundf(150.0 + roundf(-0.5)) = 149.
On the other hand, BView::ResizeBy was doing it right, and this
explains the bug in Cortex (#333). Cortex was doing
scrollBar->MoveBy(-0.5,0) then scrollBar->ResizeBy(0.5,0) and the
inconsistency lead to the visual bug. (see StatusView::MouseMoved())
This fixes#333. The bug was strange to reproduce since sometimes the
point received in MouseMoved would be "some_integer+0.5" values
sometimes just integral. This has still to be investigated though not
problematic here anymore. See cortex/RouteApp/StatusView.cpp line 222.

in Cortex). This happened only when needing a tabbed view. It will now return a view with the
most fitting size. This fixes#597

we now double/halve the current size of the list, starting with the constructor blocksize as a baseline.
This has the net effect that when doing large numbers of inserts/removes, the number of resize operations
needed scales logarithmically to the number of operations, which should yield a decent performance
improvement in such cases.
Review welcome. This does not yet affect ticket #2363 that I'm aware of, as I'm currently in the process
of attempting to find a copy of said app to test with.

always Bounds() now.
This fixes#361, again we're better than R5! Although in this test case, the scrollbars shouldn't be activated in the first place. In icon mode the poseview is still putting too much white space on
the left (x<0) and make the scrollbars show. Fix is almost ready :-)

Should actually not be mush slower than the old version, and hopefully makes
it possible to have smarter BView::Draw() implementations which should make
more than up for any potential speed loss.

play any more clips." Of course I was searching in my own commits. In the
end, I resorted to binary searching revisions for when this broke. Turns out
it is your change r25793/r25794, in which you forgot to attach the colorspace
to the app_server message. Which of course makes it lock up. Another of those
instances where you think passing data structures between client and app_server
instead of this "protocol" would be the better idea...
* Fixed bitmaps_support_space() retrieving the currently supported overlay
flags for a given color space. This makes MediaPlayer play files again, the
media node connection would time out because of the broken app_server
communication. (I have not tested this change yet, but I will in a minute, on
a different computer.)
* Also retrieve the overlay supported flag for YCbCr colorspaces.

* Added B_BITMAPS_SUPPORT_OVERLAY flag to indicate overlay support for the
color space.
* Rewrote GraphicsDefs.h - the previous one was obvious a copy of the Be header,
including typos and strange white space. I was a bit lazy with respect to
the color space details, and mostly trusted the information provided by the
Be header else.

to give other windows the opportunity to mark the icon invalid before
recaching it.
* Since we currently update all app MIME types on first boot, over 400 messages
are generated, so that delay easily caused the message queue to get full.
* I've now reduced the wait to 10 ms, and also call BWindow::UpdateIfNeeded()
afterwards, which empties the message port, too. This fixes bug #2212.
* Note though, this should be handled completely different to make it really
work right.

* Moved quite a few private kernel headers to the new location. Split
several kernel headers into a shared part and one that is still kernel
private. Adjusted all affected Jamfiles and source in the standard x86
build accordingly. The build for other architectures and for test code
may be broken.
* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly
kernel-only should be moved to some other place (maybe
headers/private/shared/util).
