Comment(by dustymugs):

 Strange set of regression failures as the functions failing aren't related
 and functions related to the ones failing aren't.

 The mapalgebraexpr failure appears to be caused by a rounding issue.  The
 specific test that is failing is rounding a pixel value of 27.5, which
 could go to 27 or 28 depending on the platform.  I'm going to change the
 round() to a ceil() as that should be more consistent across all
 platforms.

 It looks like the output queries in rt_clip aren't explicitly ordered like
 they should.

 Can you try r9858 for 2.0?  I've also committed the change for trunk in
 r9858.
