Fix (unreported): TextureOperation inputs have no resolution

When compositor node tree has a texture node, TextureOperation vector inputs  has always {0, 0} resolution instead of having same resolution as TextureOperation which is the expected behaviour for resolutions propagation.

Current TextureOperation determineResolution implementation doesn't determine inputs resolution, breaking propagation of preferred resolution and that's the reason why they are always 0. Setting scene resolution always would mean it is its own resolution and could make sense, but setting it only when preferred resolution is 0, breaks preferred resolution logic affecting other operations as explained in D10972. In any case scene resolution is already the default preferred resolution on viewer and compositor nodes.
