Created project to test render to texture
Added GL methods to DriverGPU. Fixing FBOs and Texture 4 rendering2texture. There is an error with GL method order... bind, unbind, and so on...
testing render2texture pipeline.
Debugging render2texture. Why INVALID_VALUE when using stored attachment in FrameBuffer class?
Solved error with fbos. While storing texture as attachment a local texture was created and deleted and that causes INVALID_VALUE in GL
Texture save method fixed
Work with gDebugger but not with vs...
modified pipeline of test loadtexture
Gog render2texture tutorial working with opengl functions directly (no GLHL classes)
Fixed trouble with fbo in render to texture.
Re-arranging repo files. Designing new GLHL base interface to use windowless, windowed or multiple window contexts.
Erased undefined function in DriverGPU
Changed guards according to new folder structure. Created Context.h file.
Created test to design context class
Made safe multi-context  creation (Multi-window)
Coding Context class and context creation
First approximation of windowless context creation
render without window seems to work. but thing that a windows is also created but not shown. Is any difference?
Created context class for linux but not tested. Added methods to make current contexts and windows. Tested context test with VS13 and seems to be right, but gdebugger found some error
Adapted render2texture test to new lib folder structure
