Show Texture+Attribute in Solid Viewport shading for GP

the Solid Viewport shading allows to show either "texture" or "Attribute". For grease pencil, it is useful to: show texture for textured brushes, but that will not show the "Color attribute", and the stroke will appear as black.

It would be very useful to be able to show both the color and the texture of the brush in solid mode. the "Material" and "rendering" shading modes cost more performance and they depend on the lighting (instead of showing the actual colors).
