I have fallen to the problems of compile context and sharing lists
(wglShareLists, glXCreateContext(x,x,true,x)).
They share display lists, VBO/IBO, shaders, textures, FBO, PBO.
But how is it with rendering capabilities, e.g. is OSG compile context
and "shared" OpenGL context guaranteed to have the same OpenGL version
and the same extensions available? I am looking for general case that
include systems with several various graphics cards or even remote
rendering setups with OSG.
For example, I may create OpenGL 4.0 style shader in compile context
because it indicates that OpenGL 4.0 is available, but can I relay on a
presumption that rendering context will support OpenGL 4.0 as well?
Or even worse scenario - the user may specify arbitrary context for
sharing in traits. Will it break above mentioned things?
Thanks,
John
