Created attachment 6611 [details]
sample

i've used mupdf since 0.2 :) but for some reason between 0.5 and 0.6 (nearly 0.7)
the rendering of this and other pdf's like it have become blurry 


the test file is:

[Limitations of Record-Based Information Models (William Kent, 1979)](http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.86.4262); (10.1.1.86.4262.pdf, sha1:29b75dc428b7ea014b421d1ee901d6bc2c5cb494)

each page is 22 CCITTFax 1950x134 1bpc and 1 CCITTFax 1950x52 1bpc bands from the shortening of CODASYL on the sample the bands are being stretched and are overlapping

the code used for drawing images fz_drawfillimage doesn't have the same result as renderimage in 0_5 did

The current code (today's date is september 27) renders sharper than ever before, using the smooth scaling code. It's still very slow, but we will improve performance before the 0.8 release.
