* Improve performance of panning the viewport with OpenGL renderer * Use a shader to perform the copy rect operation * Clear the frame buffer after its initialized * Handle Y flip in shader, be explicit about FBO draw state * Target 330 core, remove the y flip handling * Explicitly use GL_RGB8 and not GL_RGB * Add more error handling, clear depth when depth is created * Lets try this * Make sure blend and depth are disabled * Bind the source fbo for reading * Try this alternative approach * Set read and draw buffer before glBlitFramebuffer * Apple is forcing my hand * Update changelog.txt
