Configuration Options
Configuration of the GUI is handled by fields in the ConfigType type. For
convenience, all of the top-level functions use a global state available
via the gui.Config global.
The following configuration options are available:
* Width
When creating a new window, this is the width
* Height
When creating a new window, this is the height
* Debug
When 'true' log more output
Toolkit Usage
Right now, this abstraction is built on top of the go package 'andlabs/ui'
which does the cross platform support.
The next step is to intent is to allow this to work directly against GTK and QT.
It should be able to add Fyne, WASM, native macos & windows, android, etc.
It should be able to add Fyne, WASM, native macos & windows, android and
hopefully also things like libSDL, faiface/pixel, slint
