	// \todo [2012-10-02 pyry] Implement negative cases for following non-trivial cases:
	//  * eglBindTexImage()
	//    - EGL_BAD_ACCESS is generated if buffer is already bound to a texture
	//    - EGL_BAD_MATCH is generated if the surface attribute EGL_TEXTURE_FORMAT is set to EGL_NO_TEXTURE
	//    - EGL_BAD_MATCH is generated if buffer is not a valid buffer (currently only EGL_BACK_BUFFER may be specified)
	//    - EGL_BAD_SURFACE is generated if surface is not a pbuffer surface supporting texture binding
	//  * eglCopyBuffers()
	//    - EGL_BAD_NATIVE_PIXMAP is generated if the implementation does not support native pixmaps
	//    - EGL_BAD_NATIVE_PIXMAP may be generated if native_pixmap is not a valid native pixmap
	//    - EGL_BAD_MATCH is generated if the format of native_pixmap is not compatible with the color buffer of surface
	//  * eglCreateContext()
	//    - EGL_BAD_MATCH is generated if the current rendering API is EGL_NONE
	//	  - EGL_BAD_MATCH is generated if the server context state for share_context exists in an address space which cannot be shared with the newly created context
	//	  - EGL_BAD_CONTEXT is generated if share_context is not an EGL rendering context of the same client API type as the newly created context and is not EGL_NO_CONTEXT
	//  * eglCreatePbufferFromClientBuffer()
	//    - various BAD_MATCH, BAD_ACCESS etc. conditions
	//  * eglCreatePbufferSurface()
	//    - EGL_BAD_MATCH is generated if the EGL_TEXTURE_FORMAT attribute is not EGL_NO_TEXTURE, and EGL_WIDTH and/or EGL_HEIGHT specify an invalid size
	//  * eglCreatePixmapSurface()
	//    - EGL_BAD_ATTRIBUTE is generated if attrib_list contains an invalid pixmap attribute
	//    - EGL_BAD_MATCH is generated if the attributes of native_pixmap do not correspond to config or if config does not support rendering to pixmaps
	//    - EGL_BAD_MATCH is generated if config does not support the specified OpenVG alpha format attribute or colorspace attribute
	//  * eglCreateWindowSurface()
	//    - EGL_BAD_ATTRIBUTE is generated if attrib_list contains an invalid window attribute
	//    - EGL_BAD_MATCH is generated if the attributes of native_window do not correspond to config or if config does not support rendering to windows
	//    - EGL_BAD_MATCH is generated if config does not support the specified OpenVG alpha format attribute or colorspace attribute
	//  * eglMakeCurrent()
	//    - EGL_BAD_MATCH is generated if draw or read are not compatible with context
	//    - EGL_BAD_MATCH is generated if context is set to EGL_NO_CONTEXT and draw or read are not set to EGL_NO_SURFACE
	//    - EGL_BAD_MATCH is generated if draw or read are set to EGL_NO_SURFACE and context is not set to EGL_NO_CONTEXT
	//    - EGL_BAD_ACCESS is generated if context is current to some other thread
	//    - EGL_BAD_NATIVE_PIXMAP may be generated if a native pixmap underlying either draw or read is no longer valid
	//    - EGL_BAD_NATIVE_WINDOW may be generated if a native window underlying either draw or read is no longer valid
	//  * eglReleaseTexImage()
	//    - EGL_BAD_MATCH is generated if buffer is not a valid buffer (currently only EGL_BACK_BUFFER may be specified)
	//  * eglSwapInterval()
	//    - EGL_BAD_SURFACE is generated if there is no surface bound to the current context
	//  * eglWaitNative()
	//    - EGL_BAD_CURRENT_SURFACE is generated if the surface associated with the current context has a native window or pixmap, and that window or pixmap is no longer valid
