I am trying to draw elliptical gradients as well as radial ones. What would be the best approach to implement something like this?
The `RadialGradient` allows only one radius in the definition.

Do you have a mock of what you are trying to build?

We added support for 2 focal point radial gradients in Android 12. If you would like to leverage this in compose you can create a `ShaderBrush` that creates an instance of this gradient for devices running Android 12+.
<https://developer.android.com/reference/android/graphics/RadialGradient#RadialGradient(float,%20float,%20float,%20float,%20float,%20float,%20long[],%20float[],%20android.graphics.Shader.TileMode)|https://developer.android.com/reference/android/graphics/RadialGradient#RadialGradient(float,%20float,%20flo[…],%20android.graphics.Shader.TileMode)>

Depending on the implementation you might be able to do so with multiple RadialGradient implementations with a ComposeShader in Android.

I want to create the following type of gradient so that I can place text in the lower right corner over the background graphic.

So we currently don't have support for matrix transformations of shaders in compose, however you can create an android.graphics.RadialGradient with a horizontal scale applied to a matrix passed to `setLocalMatrix` and wrap this with a `ShaderBrush` to get the desired effect
