#340 Compile error in colorhistogram.h in decorate_base plugin

[Eric Smith]

I maintain the Meshlab package for Fedora Linux. When I try to update the package from 1.3.1 to 1.3.2, I get a compile error (from GCC 4.7.2):

In file included from decorate_base.h:29:0,
                 from decorate_base.cpp:24:
colorhistogram.h: In member function 'void vcg::ColorHistogram<ScalarType>::Clear()':
colorhistogram.h:43:11: error: '::::Clear' is not a class member

The error occurs on the first statement of the Clear() method:

void Clear() {
this->::Clear();
CV.clear();
}

I've never seen C++ syntax like "this->::Clear()" before. It that supposed to invoke the superclass' Clear method?

If you commit a fix for this to the repository, then update this ticket, please include an explanation of which commit fixed it. With issue #292, it was just closed as fixed, but I wasn't able to identify where the fix actually occurred.

Thanks!
Eric

Has not change between 1.3.2 and SVN.
