Also, GLCtrl have a strange behavior concerning context (A behavior I changed in my own GLCtrl) :

When ExecuteGL is call, in original version it do this :

void GLCtrl::GLPane::ExecuteGL(HDC hDC, Event<> paint, bool swap_buffers){
    /**** CODE ****/
    wglMakeCurrent(hDC, s_openGLContext); //Hooking the OpenGL Context
   /***** Code / Swap buffer etc .... *****/
   wglMakeCurrent(NULL, NULL); //Releasing the current OpenGL Context
}

This aquisition then releasing is problematique since it prevent you to execute some OpenGL code outside of GLPaint function.

Hello Mirek,

It seems that we have all information to update glew.

if (glewIsSupported("GL_VERSION_4_3")) enhanced_mode=true;

instead of

if (glewIsSupported("GL_VERSION_2_1")) enhanced_mode=true;

Do we need it?

BTW, This string should be defined in one place to change it more easily. Right now to change it we need to modify two source files (Win & X11).

This is needed so that you can have multiple GLCtrls in multiple windows. If you need to execute OpenGL code outside of GLPaint function, just use ExecuteGL (it is in fact inteded for that use).

Hello Xemuth,

It seems that Mirek push fix with GLEW_STATIC. Also OepnGL_gald can be removed from bazzar to do not produced unnecessary confusion which GLCtrl should be used. Will you remove it?

plugin/glad also seems unnecessary now. And trust me the less package to maintain the better
