Extended Performance Monitor [stebler]

This displays the game's built-in (from the EGG library) performance monitor and adds an additional bar to it.

Overview of mkw's main loop:
1. Wait on the video interface to make sure we are at the beginning of a frame.
2. Call SceneManager::draw, which will traverse the game engine's hierarchy and call the draw method of every element, which will send commands to the GPU.
3. While the GPU is processing commands, call SceneManager::calc, which will traverse the game engine's hierarchy the same way and call the calc method of every element, which will update their respective internal state for the next frame.
4. Wait for everything to complete.

What the bars measure:
Red: total frame time.
Green: SceneManager::draw.
Blue: time spent by the GPU.
Pink (custom bar): SceneManager::calc.
