## Objective Use the "standard" text size / placement for the new text in these examples. Continuation of an effort started here: https://github.com/bevyengine/bevy/pull/8478 This is definitely not comprehensive. I did the ones that were easy to find and relatively straightforward updates. I meant to just do `3d_shapes` and `2d_shapes`, but one thing lead to another. ## Solution Use `font_size: 20.0`, the default (built-in) font, `Color::WHITE` (default), and `Val::Px(12.)` from the edges of the screen. There are a few little drive-by cleanups of defaults not being used, etc. ## Testing Ran the changed examples, verified that they still look reasonable.
