While this is not strictly necessary for this experiment,
this is something we should try to establish early:
A »play control« should be handled as an independent UI element,
without tying it logically with some viewer (or timeline); the reason is
that such a play control needs a set of very well designed keyboard bindings,
and thus we will attempt use a focus concept to link to some active viewer
instead of creating one primary viewer, which gets the benefit of the
well accessible keybindings.
Basically we want to create an explicit association between
- a timeline
- some viewer
- a play-control
Introducing a new kind of panel shows again that the `PanelManager`
needs a rework; everything there is way too much ''hard wired''
And the new panel with the play control needs an **Icon** — which is
a challenge in itself; my proposal here is to build on the film metaphor,
and combine the symbol of "Play / Pause" with an stylised film or tape player
(with the secondary idea that this icon also somewhat looks like a owl face)
- need to simplify the design to make it effective
- add small sharpening seams and balance with drop shaddow
- reorder the lightening/drakening bevels to work properly
on top of various background colours
rework each of the 32px, 48px and 16px variants
so that the shape appears clear and succinct when rendered,
taking the aliasing into account; fine-tune and balance shadows.
Since this is one of the most central concepts in Lumiera,
and this Icon is expected to become a hallmark of the Lumiera UI,
it seems adequate to spend about two days on this graphic work.
Create an Icon or Emblem to represent the Placement concept.
Alluding to an Anchor, a Hook and the Letter "P"
This expands upon an Idea conceived some years ago
and used thus far within architecture and design diagrams
- remove unreferred definitions
- remove redundant style settings
- place bounding box tiles uniformly
- establish a standard stacking order
- introduce a naming scheme for the IDs
The reason for this pedantry is to simplify maintennance,
and to make the actual changes stand out clearly in Git
