Question regarding FloatingActionButtons coloring.
## About this issue
Hey,
i have been using this awesome library for a while now and everything works pretty smoothly overall, but I ran into an issue when it comes to FloatingActionButtons.

The button looks like this:
```kotlin
    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/button_edit_toggle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginEnd="16dp"
        android:layout_marginBottom="16dp"
        android:clickable="true"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent" />
```

The icon is set via Kotlin at runtime:

```kotlin
val icon = IconicsDrawable(requireContext(), OutlinedGoogleMaterial.Icon.gmo_android).apply {
            colorInt = Color.WHITE
            sizeDp = 50
        }
editToggleButton.setImageDrawable(icon)
```

The icon of the button still appears black, even though I set the color to white. Is this some limitation of the library when it comes to these drawables or did I something wrong here?
This scenario works perfectly fine with the IconicsImageView btw.
