Comment 1 for bug 1217752

Reproduced on OS X 10.7.5 with current trunk (r12487) if applying a raster extension to a transformed bitmap image (either transformed within inkscape (scaled, rotated, skewed), or scaled on import due to the new enforced default settings which scale the imported bitmap image based on the dpi information stored in the original bitmap image)

Testing with archived builds:
- not reproduced with r12226
- reproduced with r12228 and later revisions.

AFAICT the regression was introduced with the changes in r12227/12228 (bitmap downsampling, see bug #804162):
