Public Attributes
float	bottom_edge
float	left_edge
	The position coordinates of the screen edges. These members are in terms of the map grid 16x16 pixel coordinates that map objects use. The presense of these coordinates make it easier for map objects to figure out whether or not they should be drawn on the screen. Note that these are not used as drawing cursor positions, but rather are map grid coordinates indicating where the screen edges lie.
uint8	num_draw_cols
	The number of columns and rows of tiles to draw on the screen.
uint8	num_draw_rows
float	right_edge
int16	starting_col
	The column and row indeces of the starting tile to draw (the top-left tile).
int16	starting_row
float	tile_x_start
	The x and y position screen coordinates to start drawing tiles from.
float	tile_y_start
float	top_edge

Detailed Description

Retains information about how the next map frame should be drawn.

****************************************************************************

This class is used by the MapMode class to determine how the next map frame should be drawn. This includes which tiles will be visible and the offset coordinates for the screen. Map objects also use this information to determine where (and if) they should be drawn.

Note:: The MapMode class keeps an active object of this class with the latest information about the map. It should be the only instance of this class that is needed.
