Bug: Generated Texture doesn't support scale mode since 8.1.0

[stevenwithaph]

Current Behavior

Creating a texture through app.renderer.generateTexture, applying scale mode to nearest, and then scaling a sprite will result in a blurry sprite.

Expected Behavior

Scale mode to be applied.

Steps to Reproduce

Playground link

Change pixi version from 8.1.0 to 8.0.5 to see changes.

Environment

• pixi.js version: 8.1.0
• Running Example: https://www.pixiplayground.com/#/edit/tV-S7TGoo3yiRxZ3WZUWV

Looked into this more and it seems that the issue is with the webgl renderer.
Works fine with webgpu.

The reason this happens is that the texture style is set when its created to render the item. It kind of accidentally works in WebGPU :)

Here is the amended playground that shows how to set the scaling:

There are two ways:

1 (preferred) When calling generate texture you can pass in texture options:

   const graphicsTexture = app.renderer.generateTexture({
        target: graphics,
        // set texture options at creation:
        textureSourceOptions:{
            scaleMode:'nearest'
        }
    });

2 The second is once a texture is created, the style can be modified, but update needs to be called to let the renderer know that the style has been updated:

    graphicsTexture.source.scaleMode = 'nearest';
    graphicsTexture.source.style.update();

Hope this helps!
