Detailed Description

Helper class to make the shared GL context current.

Example:

class MyTexture {
public:
    MyTexture() : _textureId(0) {
        // allocate from the shared context pool.
        GlfSharedGLContextScopeHolder sharedContextScopeHolder;
        glGenTextures(1, &_textureId);
    }

    ~MyTexture() {
        // delete from the shared context pool.
        GlfSharedGLContextScopeHolder sharedContextScopeHolder;
        glDeleteTextures(1, &_texureId);
        _textureId = 0;
    }

    // The caller is responsible for making sure that a suitable
