Refactoring

Reusing the class FilterConv1D in FilterGaussian1D for CPU and OpenGL.
Improving filtering for OpenGL

- Improved convolution for CPU and GPU
- Added mean filter for OpenGL
Refactoring OpenGL filters

- Refactoring OpenGL filters;
- Added Max and Min 2D filters in OpenGL;
Fixing bug

- Corrected a small shader bug in FilterGLBilateral2DS
- Working on fixing the OpenGL Bilateral Grid
Improving OpenGL Filter

- refactoring OpenGL filters;
- fixing bilateral grid;
FilterGL changes

- polished and tested FilterGLBilateral1D, it now uses FilterGL1D to
reuse code;
- polished and tested FilterGLBilateral2DF;
- added instructions for installing piccante;
Fixed bug in the grid bilateral filter

- The bug is now fixed and FilterGLBilateral2DG works!
Eigen Update

- added new Eigen 3.2.2 which has several bug fixes;
- working on tone mapping for OpenGL;
OpenGL improvements

- Added and tested FilterGLWarp2D for warping an image using  3x3
matrix;
- Added and tested Poisson Descriptor for describing features in a
point. This descriptor
is based on Poisson-disk distribution of samples;
OpenGL color conversion

- added OpenGL color conversion classes
- added RGB to sRGB color conversion class
- polishing OpenGL filters
Moved
Polishing

MAC OS X testing

- updates were tested on mac os x with success;
- minor adjustments for os x
color transform...
Color conversions in OpenGL

- improved the color conversion framework under OpenGL
Color conversions in OpenGL

- refactoring for adding in the ColorConvGL RGB to HSL;
