Fixes #24.

Scrollable section in the tour example

This PR adds a Scrollable widget that can be used to show an infinite amount of content vertically with a scrollbar.

  • Scrolling can be controlled by using the mouse wheel, a touchpad, or dragging the scrollbar directly.
  • The widget event logic only needs to know when the cursor is over the scrollbar, staying renderer-agnostic.
  • A scroll example showcasing a Scrollable has been created.
  • A new Clip primitive is supported by iced_wgpu, which unlocks basic layering capabilities.

Pending work

  • Replace nalgebra dependency in iced_wgpu with something more lightweight.
  • Finish and merge wgpu_glyph scissoring support. Tracking in Debug view #38.
  • Fix text caching. glyph-brush does not allow to perform multiple draw calls without trimming the glyph cache in an easy way. Tracking in Debug view #38.
  • Update tour to contain a scrollable section.
