views don't have a valid screen clipping yet. If then later we want
to invalidate the clipping of an entire hierarchie, the traversal stops
before reaching some of the child views, because the assumption was that
for any views with invalid screen clipping, their child views have invalid
screen clipping as well. Though this might cost a little performance, we
always invalidate the screen clipping of all child views, ignoring the
flag of the current view. Fixes ticket #1198 (garbled screen clipping of
E-Mail prefs and WonderBrush tool area when switching tabs).

during a short phone session with stippi :-)). This fixes bug #1714.

commented out code that give you some visual feedback on this problem
(ViewLayer::MarkAt()).

* If two intersecting windows didn't change their position but their
order, the dirty region wouldn't contain the region that would need
to be updated because of that order change. This fixes bug #827.
* When a hidden window was on the new workspace (but not on the old one),
its region would be included in the dirty region, but shouldn't have
been. This caused the app_server to update a larger region than
necessary.

* improved naming of some private BView functions and used our underscore
prefix
* added a _DrawAfterChildren method to BView which does the necessary setup
and calls the DrawAfterChildren hook
* call the new _DrawAfterChildren method in the BWindow implementation, this
was easy since the view tokens are already hierachically sorted
* implement support for B_DRAW_ON_CHILDREN in the app_server's ViewLayer, it
simply means that children are ignored for the views clipping region, any
drawing methods will paint over children (therefor the B_DRAW_ON_CHILDREN
flag is even properly named)
With these changes, support for B_DRAW_ON_CHILDREN and the DrawAfterChildren()
hook are implemented and behave exactly as on R5 as far as I can tell, also
for the view background painting.

directly (so that it can take hardware limits into account).

of locking before processing the message (single/all window lock)
-> in most message cases, I could comment out the unlocking/locking which
switched to the different lock, because the required lock is now already held,
this removes some race conditions which were commented in the code already
* EventDispatcher::SetDragMessage() didn't lock the object, this would have
been bad if multiple windows tried to set a drag bitmap at once
* the Desktop object keeps track of mouse position and pressed buttons, so
that it doesn't need to lock the EventDispatcher for sending fake mouse
moves to windows on show/hide of windows (solves some cases of possible
dead locks with the new locking strategy)
* the keyboard EventFilter switches the current workspace asynchrnously from
the Desktop thread (another source of possible deadlocks)
* the "reader is trying to become writer" check in MultiLocker is only used
in DEBUG mode now
As a summary: It would be nice if ServerWindow used a readlock for all messages
it processes itself, and forwards all messages for which it needs a write lock
to the Desktop thread. All cases where either the Desktop or the ServerWindow
mess with the EventDispatcher are possible sources of deadlocks. This is solved
right now by making sure that the lock is released before using the
EventDispatcher.
I have not observed any deadlocks while switching workspaces and launching
many apps anymore, neither crashes. But I have not tested extensively except
for in the test environment. That being said, I could reproduce the problems
on first try before in Haiku.

Now, they behave more like floating app windows, just that they float above
all other application windows, such that all window feels (also BWindowScreen)

* Since the app_server launched the input_server, it would also get notified
when the latter died via a signal - but LinkReceiver could return B_INTERRUPTED
in that case (it didn't check the return value of port_buffer_size()) which
the app_server misinterpreted and quit itself... this fixes the hanging part
of bug #1298.
* But the input_server still wasn't restarted, because the Registrar had it
still listed as being running. Now, the Registrar checks not just periodically
for died teams, it will also check for it when a new application registers
itself. This fixes the rest of bug #1298.

this for a long time... what happens when the app_server has requested a
redraw, but the client sends some drawing commands before starting the
redraw session? This would be the case, for example, when TextViews got
notified of their parent window becomming active (they would invert the
selection outside of any update session). When there was an additional
expose event, the app_server would already have the background cleared, so
the lonely "invert" command would invert the freshly painted background. Then
the normal Draw() of the TextView would be called because of the expose event.
By the time the text was rendered, it was rendered on the inverted background,
then the normal Draw() contained another "invert" command to invert the
region of the selection. Thus inverting just the text, and the background
twice. Solution:
* introduced a special handling for drawing commands arriving between
requested update session and beginning of that session: the pending
update region is clipped from the region the client is allowed to draw in.
* fixes funny text rendering in the selected part of text views. For example
ticket #908.

* with this change, there is quite a bit of cleanup, text drawing is now
about 20% faster than before the original changes to font caching,
mostly due to turning off the kerning feature, which at the moment
gives absolutely no benefit. The correct way of doing it might be to
use kerning depending on the provided glyph spacing mode
* removed fPenLocation from Painter, the usage should be more correct now,
since it is now consistently applied before the coordinate transformation
from view to screen (also for DrawShape() now, before any view scaling
and origin offset)
* Painter no longer has it's own instance of a ServerFont, instead it uses
its AGGTextRenderer instance, which was per Painter again after the
last change, and not global anymore, made _UpdateFont() useless
* When using GlyphLayoutEngine, it supports a second pass with the same
FontCacheEntry through the introduction of a FontCacheReference. This
speeds up DrawString a little, since it needs to calculate the bounding
box for the string, and then draw the string in a second pass. This is
now done with only one FontCacheEntry lookup
* I also tried to optimize the on-the-fly conversion of UTF8->CharCode away,
since it was done four times per DrawString, but surprisingly, it proofed
to be a slight slowdown.
* introduced a shortcut in DrawingEngine::DrawString() which avoids
calculating the bounding box, we are now a tiny bit faster to figure
out that we don't need to draw any string than Dano
In the test environment (drawing to offscreen bitmap and blitting to
screen eventually), text rendering is now about 3.7 times _faster_ than Dano
text rendering (directly to screen), for untransformed text. Unfortunately
I cannot test on the same machine in accelerant using version of the test
environment.

coordinate conversion (temporarily breaks shape rendering, will be fixed
in next commit)

removed font_support folder
* ServerApp can use ServerFont::StringWidth() directly again
* more ServerFont functions implemented via GlyphLayoutEngine and
custom consumer
* extended GlyphCache data structure to hole the left/right insets
of the glyph shape between its advance width, took it from the earlier
ServerFont implementation, have not tested if that gives same result
as R5
* TODO: implement GetGylphShapes via GlyphCache, although it might not
look as clean as it does now

* the previous AGG implementation is superfluous
* the new implementation is based on that one, but in a way that allows
read/write locking to the list of cache entries (fonts) as well as
read/write locking to the cached glyphs per individual font cache entry
* new GlyphLayoutEngine.h, which is to be the central place for layouting
glyphs along the baseline.
It handles the locking for getting the font cache entries.
It works by giving it a template class GlyphConsumer which does the
actual work.
* changed AGGTextRenderer to use the new font cache
* changed ServerFont::StringWidth(), and the bounding box stuff to use it
* changed DrawingEngine, it doesn't need the global font lock anymore
* our BFont thought that GetBoundingBoxesAsGlyphs and GetBoundingBoxesAsString
is the same, which of course it isn't, hence the two separate functions...
AsGlyphs just gets the bounding box of each glyph in a string, not treating
the string as an actual word
AsString adds the offset of the glyph in the word to the bounding box
* changed ServerProtocol.h accordingly for the different bounding box meaning
