Subject: [PATCH 1/2] shaped-texture: Pass along the snippet to the texture
tower
The snippet is used make sure the right source is sampled in the shader.
This wasn't done in the texture tower, meaning the textures from the
tower were not correct.

Subject: [PATCH 2/2] shaped-texture: Paint with the right layer snippet
When we get passed a "snippet" to the shaped texture, it's added as a
pipeline layer snippet to change how the source texture is sampled. When
we draw from a texture tower however we have allocated regular textures
which doesn't need any special layer snippet, so create separate
pipelines for those that doesn't use that snippet.
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/528
