Pebble-PathAnimation
====================
A GPath based implementation to be used in the animation framework on Pebble (SDK2.0+)
This "subclass" for the Pebble animation framework provides smooth transitions for GPath objects.
Basically one creates a GPath and then uses this framework to morph it betwenn any number of GPathInfo
layouts as long as they share the same number of path points.
A simple construction / destruction looks like this:
```C
#include "path-animation.h"
static GPath* path;
static PathAnimation* animation;
static const GPathInfo path_a { ... };
static const GPathInfo path_b { ... };
void on_window_loaded( Window* window )
{
// create the path *first*
path = gpath_create( &path_a );
// then create and setup the PathAnimation
animation = path_animation_create( path, NULL, &path_b );
// this will call layer_mark_dirty() for the window layer on each animation frame
path_animation_setup_update_layer( window_get_layer( window ) );
// all other animation_* methods except for _destroy and _set_handlers are supported
animation_schedule( animation );
}
void on_window_unloaded( Window* window )
{
// destroy the PathAnimation *first*
path_animation_destroy( animation );
// then destroy the GPath object - other way around *WILL LEAK MEMORY*
gpath_destroy( path );
}
```
See demo subdirectory for a working pebble sample (also in shown in the video link below).
I can't embed the [demo video](http://vimeo.com/83234539) here for obvious reasons but look for yourself..
