# The following has four substitutions:
# * The first one replaces the *first* argument to fuzzy() when it doesn't
# have a - in it, by replacing it with an explicit 0-N range.
# * The second one does the same for the *second* argument to fuzzy().
# * The third does the same for the *second* argument to fuzzy-if().
# * The fourth does the same for the *third* argument to fuzzy-if().
#
# Note that this is using perl rather than sed because perl doesn't
# support non-greedy matching, which is needed for the first argument to
# fuzzy-if.

nsStyleImage::ComputeActualCropRect may return false under 4 conditions
1. mType is not eStyleImageType_Image.
This function is design to be used when mType is eStyleImageType_Image.
Replace this 'if' check by MOZ_ASSERT.
2. nsStyleImage::GetImageData() returns nullptr
This function will return true if this image refers to a local-ref resource.
3. GetImage returns failure or does not return a valid imgIContainer.
It's possible. Please refers to the comment in imgReqestProxy::GetImage
at [1].
4. imageSize is empty
It's possible too. By giving a malformed image to a style image, we will hit
this condition. And this is right what we met in this bug.
Since ComputeActualCropRect may actaully return false, we should remove the
NS_ASSERTION that assume it will always return true.
