Move the buffer-swap-pending state from the compositing backends to the Compositor class. The Compositor is the only class that needs to access the state, and this way it to do it without calling through a chain of virtual functions. This commit adds two new functions to Compositor; aboutToSwapBuffers() and bufferSwapComplete(). The backends call these functions to set and reset the buffer-swap-pending state. This commit also renames a number of functions and variables to make their meaning clear. The act of promoting the contents of the back buffer to become the contents of the front buffer is referred to as posting the buffer, presenting the buffer, or swapping the buffers; rendering the buffer is what paintScreen() does.
