Rounded corners for StyleBoxTexture

[Swarkin]

I'm currently trying to make a button look modern using a gradient and rounded corners.

StyleBoxTexture seems to be missing a bunch of options which the StyleBoxFlat has, meaning I can either do a button with rounded corners and a solid color, or a gradient button without rounded corners.
It would be really nice if I could avoid creating .pngs in third party programs just to have round corners on an UI element, and instead do everything inside of Godot with a GradientTexture and some Theme Override magic.

Everything I've tried has led to this;

I've even tried setting clip_children to Clip + Draw and making a TextureRect with this gradient, which then led to the button's shadows receiving the white highlight, resulting in the same issue as in the picture above.

Already proposed in #3494 and at least one other

In this discussion OP wants to add a shader property to the StyleBox, however this is not what I was going for.
I just need the Border properties of the StyleBoxFlat to be present on a StyleBoxTexture as well, no shader stuff.

There is no "just" here - adding pretty much anything to StyleBox requires a pretty thorough rework.

To me, it sounds like we should add the ability to use a gradient as StyleBoxFlat's background instead. StyleBoxTexture is meant to be used when you have premade textures with an entirely distinct art direction, rather than flat design UI.

That would be a viable solution as well.

Simple gradients on StyleBoxFlat: done!
