  Fixed bug 2575 - Current GL context tracking fails
  
  Ronie Salgado
  
  The GL Renderer current context tracking fails when one window is used with an SDL renderer but another separate window is used with a user handled OpenGL context.
  
  Attached is a small program that reproduces this bug, at least in some Linux machines where an OpenGL renderer is provided by default.
  
  Expected Output:
  -"First window" should be blue.
  -"Second window" should be green.
  
  Gotten Output:
  - "First window" black.
  - "Second window" blue.
  
  What happened:
  The renderer created for the "first window" ends rendering into the "second window" OpenGL context.
  
  Bug location:
  
  SDL_render_gl.c - line 286 on hg:
  static SDL_GLContext SDL_CurrentContext = NULL;
  
  When making SDL_GL_MakeCurrent from the user perspective, that variable or the GL renderer is not notified about the OpenGL context change.
  
  Solution proposal:
  - Move the current GL context cache into another place global.
