Current implementation of ColorTest infinitely expand horizontally at
each redraw if included in a Window.
The effect can be see replacing the Panel in the ColorTestApp::update
with a Window:
```
egui::CentralPanel::default().show(ctx, |ui| {
egui::Window::new("Colors").vscroll(true).show(ctx, |ui| {
if frame.is_web() {
ui.label(
"NOTE: Some old browsers stuck on WebGL1 without sRGB support will not pass the color test.",
);
ui.separator();
}
egui::ScrollArea::both().auto_shrink(false).show(ui, |ui| {
self.color_test.ui(ui);
});
self.color_test.ui(ui);
});
```
The cause is the is the _pixel_test_strokes_ function that, at each
redraw, tries to expand the target rectangle of 2.0 points in each
direction.
