This macro was introduced so as to be able to be built without GLib. However, this feature was long ago removed, and in Mutter we depend on it anyway, so let's get rid of it in favor of more consistency.

|
|
*
|
|
* #CoglPathFillRule is used to determine how a path is filled. There
|
|
* are two options - 'non-zero' and 'even-odd'. To work out whether any
|
|
* point will be filled imagine drawing an infinetely long line in any
|
|
* direction from that point. The number of times and the direction
|
|
* that the edges of the path crosses this line determines whether the
|
|
* line is filled as described below. Any open sub paths are treated
|
|
* as if there was an extra line joining the first point and the last
|
|
* point.
|
|
*
|
|
* The default fill rule when creating a path is %COGL_PATH_FILL_RULE_EVEN_ODD.
