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.
