Yes, buttons are scaled:
The recommended area for most buttons is defined by :
#define IS_X_MIN 0
#define IS_X_MAX 110
#define IS_Y_MIN 30
#define IS_Y_MAX 170
So a button using up 1/4 of the avaliable area (which is ~110x140) will use up 1/4 of the avaliable area no matter what resolution the client has. It's really handy to make it this way for all clients to be able to use the same buttons without anyone missing out.
