GLIP-Lib 0.6 and Histogram-like algorithms

GLIP-Lib V0.6 is now released!

It includes some bug fixes as for example the problem of rendering in GL_RGB32F or GL_RGBA32F. It also adds support for histogram-like algorithm based on the use of Vertex Buffer Object and Vertex shaders.
HdlPBO has also been written again and base on a new handle called HdlGeBO (Generic Buffer Object) which is the base class for both VBO and PBO.

Histograms are now processed as entire set of points, for instance a 640x480 grid of dots in 2D space, and managed by vertex shaders with Vertex Texture Fetching (e.g. reading a texture directly from the Vertex shader). It enables us to change the destination of the "pseudo-pixel" in real-time and without cross-binding (PBO to VBO). Using this method, we can also share many informations from the vertex program to the fragment program very easily.

Unfortunately, the documentation will be release latter...

Any suggestions or issues report are welcome!
