- Fixing mapeditor move building and improving some related mapeditor stuff. Details: - Change the way exit grids are add, remove, save and load through editor, also add undo option for exit grids and you can place unlimited number of them. - Fix incorrect gridno save in temporary map file for bigmap exit grids. - Increase maximum number of light sprite from 256 to 4096 per map. - Using DEL key for QuickEraseMapTile will now erase ItemPool too, and with improved function DeleteStuffFromMapTile will erase light sprites, exit grids and door locks. - Cliff hang tiles used for middle cliffs are now possible to erase with when erase button is on. - Add support for undo door locks, also you can now erase them if erase button is on. - Move building function is completely rewrite and will properly move exit grids, door locks, lights and items too. - Removing unnecessary tiles during copy building is improved too. - Fix undo function for light sprites which now will also store all three types and undo them properly. - Fix CTD situation if tile elements are deleted and after that items too, then undo will crash mapeditor. - Fix spawning of item pool cursors during when adding items. - Fix text glitches over door locks form. - Fix sticky tooltip when loadsave screen or door locks form is active. - High ground marking cursors will not be drawn in invisible map tiles anymore to increase speed and maybe fix some render problems but I doubt it. - Move GLOCK_17_ForUseWithLOS item generation from init.cpp to los.cpp to avoid potential problems if global world items array not set. git-svn-id: https://ja2svn.mooo.com/source/ja2/trunk/GameSource/ja2_v1.13/Build@7004 3b4a5df2-a311-0410-b5c6-a8a6f20db521

/****************************************************************************************

|
* JA2 Lighting Module
|
|
*
|
|
* Tile-based, ray-casted lighting system.
|
|
*
|
|
* Lights are precalculated into linked lists containing offsets from 0,0, and a light
|
|
* level to add at that tile. Lists are constructed by casting a ray from the origin of
|
|
* the light, and each tile stopped at is stored as a node in the list. To draw the light
|
|
* during runtime, you traverse the list, checking at each tile that it isn't of the type
|
|
* that can obscure light. If it is, you keep traversing the list until you hit a node
|
|
* with a marker LIGHT_NEW_RAY, which means you're back at the origin, and have skipped
|
|
* the remainder of the last ray.
|
