Disable part of the gdimagerotate test on architectures such as i686
|
||
|
|
where intermediate floating-point operations are done with 80-bit long
|
||
|
|
doubles, and typically later rounded to 64-bit doubles. This double
|
||
|
|
rounding causes small differences in the resulting pixel values
|
||
|
|
compared with other architectures, causing the image comparison to
|
||
|
|
fail.
|
||
|
|
|
||
|
|
Patch by Mark H Weaver <mhw@netris.org>.
