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.

BColumnListView:
- Add helper method for getting the visible rect of a given field.
Refactor SuggestTextPosition to use it.
{Tree,Table}:
- Add wrapper to retrieve table cell rect using the aforementioned
BCLV helper.
* Add a BRow default constructor that use font size to compute height.
* Min height size for Title and Row are decoupled.
* The font ratio for Title and Row are decoupled.
* For small font use min height (set to usual 16.0).
* Better baseline formula.
* Fixes#11944.
* Seems like there was no easy way to simply invalidate
a given BRow. Introduced BColumnListView::InvalidateRow().
* BRow::SetField() tried to invalidate the row, but invalidated
the listview instead of the BOutlineView responsible for
drawing the list contents. Use the new InvaalidateRow().
- Store whether or not the use of the horizontal scrollbar is desired
on the class itself. If the CLV was set to use the horizontal scrollbar,
and then asked to lay itself out while hidden, it would incorrectly assume
the horizontal scrollbar wasn't in use, and consequently repositioned its
views such that the horizontal scrollbar and outline view overlapped.
ResizeAllColumnsToPreferred().
* Automatic white space cleanup.
