Spine example page looks bad on Windows

[JCash]

The example looks jagged, suggesting it gets the wrong size or something.

Looks good on macOS (Firefox):

But poor on Windows (Edge) (blurriness may be to transferring image over chat):
Notized the jagged lines, which are even more jarring when animating.

This issue is how to tell everyone that you have a Mac Retina without saying that you have a Mac Retina 😄

The reason is because last year all materials have mipmapping disabled by default. And the original model just has HUGE sized sprites and very thin lines. When scaled down we see linear filtering issues. On high dpi devices it's not so noticeable, but on old low dpi displays of course there will be a hard “ladder”.

But if we turn on mipmapping, we will see blurred lines.

We use two solutions in our games:

• sample from the mipmap above, like texture2D(texture_sampler, var_texcoord0.xy, -1.0)
• use RGSS (a cool algorithm by Ben Golus, available in the Sharp Sprite asset).

How to solve this for this example? Maybe just pre-scale down the atlas size?

Maybe just pre-scale down the atlas size?

Sounds good!
