Coverity was complaining because we did a half-ass check against NULL only to
pass that NULL pointer on to a function that deref'd it.

a few highlights:
* BLayout now derives publicly from BLayoutItem
* Added BAbstractLayout class, which our layouts now derive from
* updated layout builders to avoid creating views when they don't need to
* updated layout classes
* updated AboutSystem to fix a little regression
* more details on #6407
* please tell me about any regressions, I've tried to find them all, but some
may have slipped by.

sync when clearing any flag that the server needs to know about.

If the view doesn't have a tool tip, pass the B_MOUSE_IDLE to the next handler,
so the parent view can show a tool tip. This makes tool tips in a column list
view possible (or at least reasonably easy).

* The BView API can probably be regarded as good enough; the implementation
might need to be improved over time (also, some things as archivability
aren't fully implemented yet). The ToolTip.h header should get public once
finalized.
* Added new B_MOUSE_IDLE message that is sent to a BView after a certain
time has passed (BToolTipManager::ShowDelay()).
* Added small test app (ToolTipTest) that shows what is already working.

storage.
* Remove reduntant information from the header (field_count vs. fields_size).
* Remove checksums previously used to validate the message passing by area
mechanism.
* Move variables that are purely used by the instance out of the header and into
the BMessage object.
* Use more sensible types for the different message fields.
* Reduce some field sizes to realistic values.
* Make size_t values into uint32 values so the message format will not change
when later moving to 64 bits.
* Pack the structures used for flat message storage so it doesn't change
because of padding.
* Fix message passing by area. It never worked because the created area was
never actually filled with any data!
* Some more allocation checks with graceful fallbacks (should be all now).
* Some more checks for negative index values (should also be all now).
* Make printing more inline with how the rest of the class works and make some
of the output more consistent.
* Also add the new unsigned types to PrintToStream() output.
* Fix printing of unknown types and invalid BMessages, it would always have
printed only the first entry respectively the same error.
* Added some clarifying comments.
* Cleanup.

was already sent by this or another view. This was already the case for the
BRect version of Invalidate(), but was forgotten in the BRegion version. I
just had an idea what the problem could be, but I think it's bogus. Needs some
investigation. Should fix ticket #4119 for the time being.

invoke the layout's InvalidateLayout() anymore. This could cause problems when
the layout caches layout related information and also updates those on calls
other than LayoutView(). A call to such a method after an InvalidateLayout()
would mark the cached info valid and the layout would use the cached info
until the first InvalidateLayout() after the next LayoutView(), even if
BView::InvalidateLayout() had been called again in the meantime.
* Introduced a new method BView::ResetLayoutInvalidation(), which must be
called by layout implementations whenever they have updated their cached
information and need further InvalidateLayout() notifications.
* Adjusted the existing layout implementations to use the method.
Fixes bug #4047.

window of the view into the application thread. This solves the
race condition with asynchronous SetViewCursor and deleting the
cursor immediately afterwards for real.
* The ServerApp now requires a reference to the current cursor,
just in case...
* Added TODOs for caching the BView token, it's currently resolved
for every single BView call that talks to the server... not good!

solved more efficiently by adding a new app_server call for this, though.
* Fixed stupid operator precedence bug that caused BView to always archive
everything, instead of only those items with their archiving flag set.
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31091 a95241bf-73f2-0310-859d-f6bbb57e9c96

BView::SetEventMask(). This fixes bug #3928.
* And while the app_server handled that correctly, BView actually did not, and
stored the wrong value.

the protocoll less prone to errors, reduces possible points of failure and
most importantly, reduces the number of function calls to the link API.
I only know the numbers for StrokeLine(), which I tested via the Benchmark
test app. With this change, drawing random colored and positioned lines
actually doubled in speed. On the BView side, the calls to
ServerLink::Attach() only halfed, while on the app_server side, the number
of calls to ServerLink::Read() is now 1/4th. It will also be worth
investigating why the link stuff is so slow at all. I also optimized
BView::DrawString() a lot in this change, but I don't have any numbers
yet. Some other commands which used multiple Attach()/Read() calls were
also optimized, at least the most important ones. Begin/EndLineArray() was
also pretty bad on the app_server side.

classes (BView, BWindow, BAlert, BButton - BTextView should be part of this,
too, to make BAlerts work).
* However, it's not that simple, because there is often no way to return an
error. Most of that code obviously assumes to be able to throw exceptions
(it's just not communicated to the caller). Maybe we should just start
documenting exceptions for R1 (and properly use exceptions later on).
* Automatic white space cleanup.

* Resolved TODO: The type of the gradient is no longer encoded twice in the
app_server link protocoll.
* Moved instantiation of the BGradient into the LinkReceiver::ReadGradient()
method.
* Check success for (at least) ReadGradient() in ServerWindow.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28150 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed a general problem with respect to overriding of the reserved
virtual function slots: instead of statically invoking the method
that corresponds to the reserved slot on the class that contains the
slot, we now invoke the virtual Perform() method. Perform() then dispatches
the method invocation to the "proper" class, i.e. the highest class in the
hierarchy that actually implements the requested method.
This fixes a crash in apps that use liblayout's MSlider class and
should fix one or other spurious bug with old apps or libraries, too.
* added new header folder 'binary_compatibility' that contains files that
define the method codes and data structures required by Perform()
* looked for and implemented all used reserved virtual slot functions to
invoke Perform() where necessary or to pass on the method call statically
(for slots that were already maintained by Be)

wrong version of ConvertFromScreen() was now used, resulting in the calculation
being computed and thrown away. This broke BMenu, probably amongst other things.

* Implemented BGradient, BGradientLinear, BGradientRadial,
BGradientDiamond, BGradientConic and BGradientRadialFocus
new Interface Kit classes.
* Implemented all the (AGG-based) backend necessary in
the app_server to render gradients (Painter, DrawingEngine)
* app_server/View can convert a BGradient layout to screen
coordinates.
* Added BGradient methods of the Fill* methods in BView.
* Implemented a test app and added it to the image as a
demo.
* Adopted Icon-O-Matic and libs/icon in order to avoid
clashing with the new BGradient class. Re-use some
parts where possible.
Awesome work, Artur! Thanks a lot. Now a more modern
looking GUI has just become much easier to implement! :-)
TODO:
* Remove the need to have gradient type twice in the
app_server protocol.
* Refactor some parts of the patch to remove duplicated
code (Painter, DrawingEngine).
* Adopt the BPicture protocol to know about BGradients.
* Review some parts of the BArchivable implementation.

const BBitmap* bitmap, BRect bitmapRect, BRect viewRect, uint32 options).
Only option so far is B_FILTER_BITMAP_BILINEAR.
* BView::DrawBitmap[Async](const BBitmap* bitmap, BRect viewRect) was accessing
the bitmap pointer without checking it. Would therefore crash when passing
NULL, unlike the other methods.
* The BPicture code already reserved room for the BBitmap flags, but did not
store the actual flags and neiter use them for anything. Since the bitmap
data is stored anyways, the bitmap creation flags do not matter. So I reused
this for the new bitmap drawing options.
* Rewrote Bitmap.h and removed the B_BITMAP_SCALE_BILINEAR flag again.
* Tried to optimize Painter::_DrawBitmapBilinearCopy32() a little by giving
the compiler better hints. There seems to be a marginal, possibly imagined
speed increase < 0.05 ms. ;-)
