GLMixer Code

Small but cool feature for the GEOMETRY view; the scaling is now really working, also for horizontally or vertically flipping the image! Minimal and maximal scales are also guaranteed.

Implemented CLONE source and started implementation of ALGORITHM sources. Also cleanned the GUI and improved the layers view.

Implemented LAYERS VIEW (and the needed depth information in the source and View classes). This pointed out a bug in the selection of the (top most) current view ; therefore the introduction of the reverseSourceSet which sorts the sources in opposite order.

Implemented blending options: this required to introduce GLEW dependency under MSWindows (non-basic OpenGL functions), therefore the several changes in common.h and qmake file.

OpenGL optimizations (from RED BOOK). Most important is the use of glSubTexture2D to replace faster the content of a texture instead of glTexture2D which creates a new one.

Bug fix in the zoom, changed SOURCE_UNIT to smaller value (better for projection), and implemented zoom best fit for Mixing View.

Cmake feature; read the SVN repository HEAD revision and use it to show the revision number in the program.
