always increment quad, mesh, text and image layer counts in wgpu layer rendering

Fixes #2700

I just hit this bug. Pesky one!

Thanks 🙇

In fact, I believe we can just avoid preparing these layers altogether as a simpler fix:

@hecrj These changes apparently broke the start_layer clipping when using draw_geometry in a custom widget. The clipping still works for text, but not rectangles:

Notice how the text is clipped to the viewport of the custom widget, but the rectangles are drawn outside the widget, on top of the buttons.

Latest master with changes from this PR reverted:

The widget code is here: https://github.com/syndicodefront/infekt/blob/3f15caa6fdc8aa381422a5a28340984de589fbb4/infekt-v2/src/gui/widget/enhanced_nfo_view.rs#L231

Am I abusing a bug here as a feature or is it a regression?

[edwloef]

It seems like the changes made here were later refactored in 3428a3d, could that commit also be affecting things? I honestly have no idea.

[edwloef]

At first glance, the replacement of scale with scale_factor in the refactoring commit looks suspicious to me. Maybe you could try switching that out and see if it fixes your issue?

@hecrj confirming it works, much appreciated!
