Various V UI Examples Continue To Fail

[Wajinn]

Attempted to run V UI examples on a Linux box and still getting notices and errors after recent update (May, 4th 2025). Below is the list of failed examples:

1. cells.v (from examples/7guis)
2. demo_chunkview.v
3. demo_style_4colors.v
4. demo_style_accent_color.v
5. child_window.v (needs app.window.update_layout() to show child window contents)

V 0.5.1 4df08e9
V UI 0.0.4
Ubuntu 22.04.5 LTS
8 cpus, 64bit, little endian, 12th Gen Intel(R) Core(TM) i5-12450HX

What did you do?

Attempted to run examples of V UI

What did you expect to see?

Expected for the examples given to work and not have notices, warnings, or errors.

What did you see instead?

In the case of the examples listed above, there were notices and errors. None of them worked properly, thus are not helpful to newbies and casuals.
