The inseparable changes necessary to support live color updating across the
system in a sane, safe, and performant manner.
BView gains:
HasSystemColors()
HasDefaultColors()
AdoptSystemColors()
AdoptParentColors()
AdoptViewColor(BView*)
SetViewUIColor(color_which, float tint)
SetHighUIColor(...
SetLowUIColor(...
ViewUIColor(float* tint)
HighUIColor(...
LowUIColor(...
DelayedInvalidate()
BWindow gains a simple helper method:
IsOffscreenWindow()
BMessage gains:
AddColor()
FindColor()
GetColor()
HasColor() * allegedly this API is deprecated, but I implemented it anyway
ReplaceColor()
SetColor()
Previous private ColorTools methods are made public and moved into GraphicsDefs:
mix_color, blend_color, disable_color
These are fully compatible with BeOS dan0 R5.1 methods and are just code cleanup
of BeOS example code under the OpenTracker license.
In addition, four new colors are created:
B_LINK_TEXT_COLOR
B_LINK_HOVER_COLOR
B_LINK_ACTIVE_COLOR
B_LINK_VISITED_COLOR
These changes are documented in their proper user documentation files.
In addition, due to a history rewrite, B_FOLLOW_LEFT_TOP has been defined and
used in lieu of B_FOLLOW_TOP | B_FOLLOW_LEFT and is included in this commit.
On the app_server side, the following has changed:
Add DelayedMessage - a system by which messages can be sent at a scheduled time,
and can also be merged according to set rules. A single thread is used to service the
message queue and multiple recipients can be set for each message.
Desktop gains the ability to add message ports to a DelayedMessage so that
said messages can target either all applications or all windows, as needed.
Desktop maintains a BMessage which is used to queue up all pending color changes
and the delayed messaging system is used to enact these changes after a short
period of time has passed. This prevents abuse and allows the system to merge
repeated set_ui_color events into one event for client applications, improving
performance drastically.
In addition, B_COLORS_UPDATED is sent to the BApplication, which forwards the message
to each BWindow. This is done to improve performance over having the app_server
independently informing each window.
Decorator changes are live now, which required some reworking.

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.

* Less flickering when drawing the label: the area of the label is now
clipped, so there is no need to fill the background again.
* Consumed the last reserved member for the bounding box of the label.
* More or less rewrote the header.
