'->' operator for AggMatrix pointing to the underlying transform object of AGG
Added poppler/AggPoint.cc to CMakeLists.txt
Removed obsolete option -Wc++11-compat
OsFmtState added. Helps to (re|)store ostream format flags and values
when writing something into an std::ostream
removed obsolete debug output in utils/pdftoagg.cc
class AggPoint to represent points and distances for the AGG library
Added AggException to report runtime_exceptions for the AGG system
Documentation of poppler/AggColorTraits.h.
Added <ostream> to make the output operators work.
output operator for poppler/AggColorRange.h added
simpler access to min/max values for AggGradient
const access to asscociated AggColorRange
use AggGradient to implement AggCanvas::fill(...)
+ added AggMatrix::Rotation(x0,y0,x1,y1) to define rotations by a vector
  pointing to a specified direction.
Merge branch 'agg_support' of ssh://kuro/git/poppler into agg_support
+ check for agg_freetype support in CMakeList.txt
+ explicitely enable exception handling in CMakeLists.txt
  if we are using the AGG backend
+ make getAngle a method of AggGradient<...>
added -g for debug build
More operations for AggMatrix and AggPoint

Allow point transformation via matrix and matrix
translation via point
get start and end point of gradient as AggPoints
Allow to calculate AggGradient angles with pre-transformation with a matrix
in my way to a proper linear graddient in AggCanvas
not all transfiormations work as expected for now
