 In a closed path, starting and ending points meet. In an open path, starting and ending point do not meet. In PyCairo, we start with an empty path.  
 First, we define a path and then we make them visible by stroking and/or filling them. After each `stroke()` or `fill()` method call, the path is emptied.  
 We have to define a new path. If we want to keep the existing path for later drawing, we can use the `stroke_preserve()` and `fill_preserve()` methods.  
-A path is made of subpaths.
+A path is made of sub-paths.
 
 A `Source` is the paint we use in drawing. We can compare the source to a pen or ink that we use to draw the outlines and fill the shapes.  
 There are four kinds of basic sources: colors, gradients, patterns, and images.

 `context.new_sub_path()` begins a new sub-path. Note that the existing path is not affected. After this call there will be no current point.  
 In many cases, this call is not needed since new sub-paths are frequently started with `Context.move_to()`.  
 A call to `new_sub_path()` is particularly useful when beginning a new sub-path with one of the `Context.arc()` calls.  
-This makes things easier as it is no longer necessary to manually compute the arc’s initial coordinates for a call to `Context.move_to()`.

 `context.set_fill_rule(fill_rule)` set a FILL RULE to the cairo context.
 
 For both fill rules, whether or not a point is included in the fill is determined by taking a ray from that point to infinity and looking at intersections with the path.  
-The ray can be in any direction, as long as it doesn’t pass through the end point of a segment or have a tricky intersection such as intersecting tangent to the path.
