Brings gioui.org/shader along to v1.0.9. This is the dependency set the
current build and on-device tests run against (go build, full test suite, and
the phone APK all pass with it).
- Element interface with Region() and Visible() methods
- Label and ListView element types with constructors
- Renderer that clips and draws elements in slice order
- Main app loop with Gioui window and frame events
