Eliminate white space around wrapfigure environments in LaTeX.

wrapfigure_without_whitespace.tex

%% The typical answer for how to eliminate white space in wrapfigure doesn't work for me (I'm using a SIGGRAPH style sheet):
%%     http://tex.stackexchange.com/questions/111393/too-much-space-around-wrap-figure
%% Instead, let's just offset the image.
%% The horizontal white space is \columnsep and the vertical white space is \intextsep.
%% Subtract them from the column width and offset the image accordingly.
%% How to move an image:
%% http://tex.stackexchange.com/questions/107340/how-to-shift-graphics-adjust-placement-of-figure-with-includegraphics
\begin{wrapfigure}[11]{R}{1in - .75\columnsep}
    %\centering
    \vspace{-\intextsep}
    \hspace*{-.75\columnsep}\includegraphics[width=1in]{path/to/image}
\end{wrapfigure}

This trick won't widen a caption, if your inset figure has one.

@yig, do you have a solution for captions?

I found an old solution I'd even commented on in the past:

Thanks a lot! I spent around 3 hours searching and finally found solution. It works!

Wow, this is very helpful!
