The current implementation of pdf+latex renders all text objects (LaTeX) above all graphical objects (PDF). I needed to export a figure with text interleaved with graphics---essentially bug #771957---so I implemented a simple fix for it.

I'd like to see this (or, more likely, a modified version) merged for 0.49, but I'm not sure who maintains the pdf+latex renderer. Please let me know how to help.

The code is at https://code.launchpad.net/~drbild/inkscape/multilayer-pdf-latex-output
