Description
Finds a free area in the texture large enough to contain a surface with the given size. If a large enough area is found, it is marked as in use, the output parameters OutBaseX and OutBaseY are set to the coordinates of the upper left corner of the free area and the function return true. Otherwise, the function returns false and OutBaseX and OutBaseY remain uninitialized.
