+Summary: Bitmap class / loading png
+Description of Problem:
+If I load some pngs(seemingly all of those which are created by image
+magick convert), well, It looks horrible.
+sample file output:
+bitmapbug $ file bitmapbug-in.png 
+bitmapbug-in.png: PNG image data, 50 x 60, 16-bit/color RGB, non-interlaced
+Steps to reproduce the problem:
+1. see example code which just saves the example input image again
+Actual Results:
+Output when saving and GetPixel very ugly
+Expected Results:
+A pretty image and correct pixel values.
+How often does this happen? 
+Always, though not with all pngs, the few ones which worked were 8-bit ones.
+Additional Information:
+Tested with mono on 2x gentoo(libgdiplus-1.2.2) and 1x debian
