BView implementation (client side)
* introduced some private methods for _Convert*(BPoint*) methods which avoid
doing the check_lock() thing in the recursion, also Origin() would likely
have communicated with the app_server all the time, since the origin bit
was needlessly invalidated, so some speedup should be achieved
* this should fix ticket #98

* 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

I "ported" the region implementation from XOrg to work on BRegion data.
This resulted in pretty much the same code structure as before, with
RegionSupport.cpp containing the messy details. Only now it _is_ really messy
from a code beauty point of view. I didn't exactly feel like cleaning it
up right now... but I guess I will have to.
So what does this mean - our BRegion implementation was very slow (no offense!),
and on top of that it scaled very badly with more and more rects. The new
implementation seems to be on par with the very fast R5 implementation and
the data looks exactly the same too. BRegion is very performance critical
for the app_server, and I cannot wait to try this on my slow computer...
Some changes are noteworthy: The right and bottom coordinates of
BRegion internal data are now exclusive! I inherited that from the
XOrg implementation and didn't feel like changing the code, seeing it
is probably tested quite well. The conversion is handled transparently.
Secondly, constructing a BRegion with just one rect is not invoking
malloc anymore for the member data, this makes it much more efficient
to use temporary BRegions with just one rect, both externally and internally
in the BRegion implementation.

* Removed storage/Alias.h as that stuff isn't even available on BeOS.

* Reworked the internal layout. _ValidateLayoutData() computes and caches the
layout related data and all other methods just use those values. Now, in
layout-aware mode the class should properly work not only when using the
layout items. And when using layout items, the class does actually do
internal layout; it was basically good luck that it worked in the tests,
before. Vertical resizing is supported, too.
* We do a few mean tricks to get the probably mostly preferred layout behavior:
By default our own explicit max width and that of the menu bar layout item is
set to unlimited and the horizontal menu bar alignment to left aligned. This
allows to horizontally resize a BMenuField beyond its preferred size,
although both label and menu bar have a limited max width. The user can, of
course, override those explicit sizes/alignments to get a different behavior,
if desired.
* Fixed invalidation in SetDivider(). When having the focus, the left and top
border of the blue frame were not invalidated.
* The label is no longer drawn at vertical position font ascent + descent
+ leading + 2 (not sure how this calculation was supposed to work), but
vertically centers the label around the ascent. With big fonts the label is
shown a bit too far to the bottom. Not sure how to fix this in a generic way.

* Don't resize the view and the window anymore, when fResizeToFit is not
set.

discussed in the thread in haiku-development. I added a fSubmenus member
to BMenu, to be able to tell from BMenuItem if there are other items
with a submenu (maintained in BMenuItem::SetSuper()). If you don't like
this solution, let's just revert.

- Menus are generally a bit wider (BeIDE ones didn't look nice)
- The modifiers bitmap are drawn more centered vertically
- Splitted BMenu::ComputeLayout() into three methods
- Various minor changes.
The menuitems still don't look nice with bigger font sizes, but we'll
try to fix this...

only invokes the BView version. Didn't know what to do with MinSize() and
PreferredSize(). ATM they return fixed, hard-coded values. It might make
sense to compute something depending on the font size, for instance.

and DoLayout(). When the B_SUPPORTS_LAYOUT view flag is set (as is by
default when using one of the new constructors) the BBox completely manages
one true child (the first child that is not the label view).
* Centralized the layout related computation in new method
_ValidateLayoutData(). The computed infos are cached in a new private
LayoutData structure.
* GetPreferredSize() was broken in several respects. It does now return the
same result as PreferredSize(). If B_SUPPORTS_LAYOUT is not set, these are
the sums of the insets induces by the frame and the label. I.e. those values
can for instance be added to the child's preferred size to compute the
preferred size of the compound.
Not sure, if the Haiku-only TopBorderOffset() and InnerFrame() functions still
make sense. With layout management they're actually superfluous.

disjunction of all view flags before, and the new layout related flags were
missing. I suppose there was not striking reason for previous method.
* Made InvalidateLayout() virtual. When implementing layout management
directly in a derived class instead of a separate BLayout, one needs to
override it to know when to discard cashed layout infos.
* Added a ResizeTo(BSize) method.
* Avoided ugly multi-line strings in PrintToStream().

Removed most data allocations/copying from PicturePlayer, ServerPicture now has to do this when converting coordinates.
Added additional functions to ViewLayer to copy&convert multiple BPoint, BRect, BRegion to Screen coordinates, those should be further optimized.
Removed some function call overhead.
Note: some functions of PicturePlayer don't appear to be implented by PictureDataWriter,

* replaced new[] with malloc()/realloc() where appropriate - since we're messing with
the bits anyway, this makes the code slightly faster.
* however, we might want to throw some std::bad_alloc exceptions to deal correctly with
low memory situations.
* cleanup.

* _ContrainPoint() was broken as it could never change the point it was supposed
to contrain.
* MouseDown() no longer sends a notification message automatically (only if it
changed something)
* MouseMoved() and synchronous MouseDown() will now only send modification messages
if something actually changed (not for every mouse update).
* After key presses, the invokation message is only sent when the value changed.

of BFont. You can BFont::SetFalseBoldWidth(float) a width on a
BFont object, and it will cause the glyph shapes to be run through
an AGG "contour converter" so that they become thicker or thinner.
IIRC, this is commonly referred to as "false bold". The "width" value
is the distance in pixels that the new glyph outline will be offset
from the original outline.
It would be nice if someone could look at my change to View.h with
regards to the B_FONT_ALL flag.
