Issue description

Vertical lines in GL are flat rectangles, that disappear at certain camera angles (sloped/horizontal lines affected too).
It looks especially bad when there are many lines, the whole map sections disappear.
They should be either line primitives (GL_LINES/GL_LINE_STRIP) or decals facing camera (billboards).

It's a feature in plan called PixelLineStringLayer which will draw lines in screen pixle width.

Currently I'm focusing on webgpu upgrade, I will implement PixelLineStringLayer after the uprade, maybe in april or may (I hope).

And happy chinese new year by the way.
