// A note about X,Y coordinates:
//
// X coordinates are in pixels, from the left edge of the window client area
// Y coordinates are in pixels, from the BOTTOM edge of the window client area
//
// The Y coordinates therefore match OpenGL window coords, not Windows(tm) window coords.
// If Y is from the top, the variable will be called "y_from_top"
