Detailed Description

This class provides functions for drawing things on screen.

It also maintains a stack of transforms that are applied to graphics.

bool DrawingContext::perspective_scale	(	float	speed_x,
		float	speed_y
	)

Recalculates the scaling factor for parallax layers.

void DrawingContext::set_flip ( Flip flip )

Apply that flip in the next draws (flips are listed on surface.h).
