Description:
Layers not marked visible should not export. I use a layer for placement labels that I don't want in the final export, so turn that layer off, but it shows up anyway.

Steps to Reproduce:
1. Launch Windows LO 
2. Create a new Draw file
3. Insert a new layer
4. Draw something on the layer
5. Set the layer to invisible (shift-click the layer's tab)
6. Export the layer as PNG/GIF (all formats affected)

Actual Results:
The layer set to invisible still exports its contents.

Expected Results:
Any layer set to invisible should not export its contents.


Reproducible: Always
