The previous implementation of automatic scrolling in LayerListWidget
relied on mousemove events to perform the scrolling, which didn't
produce the expected behavior. Instead use the new auto scroll timer.
As pointed out by Andreas, drawing them from the bottom feels odd
since no other list in the UI is bottom-justified. The commit draws
the layers from the top of the list again.
A previous commit I made broke layer dragging since the hole_index
was always being computed with respect to the top of the layer list
widget, however we were now drawing layers from the bottom. When
you didn't have enough layers to fill up the full height, dragging
them around would be weird.
This patch computes the hole index correctly using the same offset
we start drawing from, and fixes the behavior.
Previously the background layer was shown at the top, and layers
in front of it were shown below it. This was really unintuitive.
This patch fixes LayerListWidget to now properly differentiate
between the index of a gadget, and the index of a layer, since they
are essentially mirrored. I chose not to modify the order in which
layers are stored since back-to-front makes it really convenient
there.
Previously move_selection() did not work as expected. Instead store the
selected layer index in a member variable and continue to cycle through
the layers when you come to the start/end. Also use it to scroll into
view. Lastly rename the function to cycle_through_selection() to make it
clearer what it does.
This enables the layer menu as a context menu in LayerListWidget,
setting the clicked layer as active for now, but in the future it
would be nice to have custom menu applying to the clicked layer instead
of the active layer.
