Composer raster problem printing

[jctull]

A major issue has cropped up with the handling of raster data in composer output. Rasters appear to be rendered multiple times with a datum shift at each render. I've attached an example I made using the spearfish data (geology raster layer and archsites vector layer). This should be replicable, but testing by others would be appreciated. I used default settings for the composer item (A4, landscape page). Printing as raster, vector, exporting as image—all have the same result as shown below.

Raster print offset issue

I realized my test example was being reprojected to epsg 26911. Setting the native resolution as the project default generates the same general problem. Likewise, turning off OTF reprojection results in bad map output.

I confirm this problem on Ubuntu with r15505.

I was able to get a successful map produced with rev 15382, but nothing beyond that (there were separate crash issues for OSX not resolved on my platform until rev 15412, so it may have cropped up anywhere in that span of code updates).

Should be fixed in r15528. Please test and reopen if not.
