Upgrade Dispersion plugin PNG assets to SVG

[rubiefawn]

Replaces the .png raster assets for the native Dispersion plugin with .svg vector assets. nothing! it's all CSS now.

Note

Part of #7767

[rubiefawn]

Text in SVG assets isn't working properly at the moment (the DC button on the right, ignore the "AMOUNT" label). Should such buttons even be SVG since they won't inherit the correct font? Should they be styled through CSS instead?

Edit: This button is now styled through CSS.

Haven't tested but looks okay overall. Had a few suggestions/questions though:

[sakertooth]

Also wondering if any of the other plugins you've switched to SVG could use the same CSS treatment, or should they be left as SVG?

[rubiefawn]

Yes, several of them should be changed to pure CSS. I'll do those all together in a separate PR.

Very odd. Tested on the x86 Linux AppImage.

.svg vector assets. nothing! it's all CSS now.

Could you elaborate on this?

I think the elaboration is that the Dispersion plugin didn't have many PNG assets; one of them was a button with text on it, so that was converted to a button with text on it, and one of them was a solid background color, so it was converted to a solid background color.

The only thing that was changed into an SVG was the logo, which is the same LMMS logo SVG everything else is using.

There was a conflict with #7525 and I botched my merge, now the layout is all scrambled, yuck. I'll take a look at fixing the layout later tonight.

@rubiefawn Has the missing icon been addressed?

[rubiefawn]

Not yet, I haven't looked into it yet. Fixed

[bratpeki]

Tested it, looks great! Had a quick look at the code, just to make sure only GUI is affected, everything looks fine to me. Just for reference, the plugin looks like this now:

[sakertooth]

The effect looks fine, did a quick test, had some minor concerns but nothing really substantial.

[rubiefawn]

While fixing the missing tr() calls I noticed "octaves" was also missing that. Fixed all of them 👍

Looks good to me code-wise
