/*
|
||||
* NOTES
|
||||
*
|
||||
* A map is composed of submaps, which in turn are composed of rows of
|
||||
* 0x20 tiles. map_map contains the tiles for the current portion of the
|
||||
* current submap, i.e. a little bit more than what appear on the screen,
|
||||
* but not the whole submap.
|
||||
*
|
||||
* map_frow is map_map top row within the submap.
|
||||
*
|
||||
* Submaps are stored as arrays of blocks, each block being a 4x4 tile
|
||||
* array. map_submaps[].bnum points to the first block of the array.
|
||||
*
|
||||
* Before a submap can be played, it needs to be expanded from blocks
|
||||
* to map_map.
