White lines between Raster tiles with AGG renderer

[jbirch]

Jason reported:

I'm seeing a bug in rendering of image catalogs from GDAL. Essentially, I get white lines between my perfectly edge-matched tiles.

Tom followed up:

Not sure, but it looks like the problem in #4 that was fixed in the GD renderer also needs to be fixed in the AGG Renderer.

In MGOS 2.0... GD Renderer: no gaps AGG Renderer: gaps

Gahh. That's what I get for editing email to try to make the ticket sound better.
