Eventually I'd like to do some kind of bitmap layers, and we definitely want
alpha channel support then, so let's just not paint ourselves into an
uncomfortable corner early on. :^)
This needs more work and polish, but it's a step in a more pleasant and
useful direction.
Also turn QuickShow into a fully-fledged "application". (By that, I really
just mean giving it its own Applications/ subdirectory.)
Painter gains the ability to draw lines with arbitrary thickness.
It's basically implemented by drawing filled rects for thickness>1.
In PaintBrush, Tool classes can now override on_contextmenu() to
provide a context menu for the toolbox button. :^)
Left mouse button selects (and copies the selection on mouse up).
The right mouse button then pastes whatever's on the clipboard. I always
liked this behavior in PuTTY, so now we have it here as well :^)
Taskbar now simply asks the WindowServer to popup a window menu when right
clicking on a taskbar button.
This patch also implements the "close" menu item, and furthermore makes the
window menu show up when you left-click a window's titlebar icon. :^)
Put together a pretty well-performing queue using a Vector and an offset.
By using the new Vector::shift_left(int) instead of Vector::take_first()
we can avoid shifting the vector contents every time and instead only
do it every so often.
Maybe this could be generalized into a separate class, I'm not sure if it's
the best algorithm though, it's just what I came up with right now. :^)
I've used a SinglyLinkedList<Point> for the flood fill queue, since Vector
was death slow. This could definitely be made faster with a better algorithm
and/or data structure. :^)
I originally called it "linear" because that's how the Intel manual names
virtual addresses in many cases. I'm ready to accept that most people know
this as "virtual" so let's just call it that.
We should work towards a pattern where we take StringView as function
arguments, and store String as member, to push the String construction
to the last possible moment.
GWindow::move_to_front() can now be used to move a window to the top of
the window stack.
We use this in Terminal to bring the settings window to the front if it
already exists when it's requested, in case it's hiding behind something.
