prevent double draw in render-tests

[asheemmamoowala]

Move text and camera off tile boundaries to prevent double drawing of symbols.

In support of passing tests in gl-native port

Chris Loer @asheemmamoowala The double-drawing is actually a larger underlying bug that I think we should address, but for now with the test, the right approach might be to just make it irrelevant by shifting the labels so they’re not near a tile boundary and thus don’t get double-drawn

Here's the relevant issue that these tests are interacting with: #2706

It would be interesting to know why the double-drawing isn't happening in gl-native -- I thought the logic was the same.
