@@ -10,7 +10,7 @@ This part of the guide will assume that you have read the byond reference entry
 
 When you create an atom, this will always create an internal byond structure called an "appearance". This appearance you will likely be familiar with, as it is exposed through the /atom/var/appearance var. This appearance var holds data on how to render the object, ie what icon/icon_state/color etc it is using. Note that appearance vars will always copy, and do not hold a reference. When you update a var, for example lets pretend we add a filter, the appearance will be updated to include the filter. Note that, however, vis_contents objets are uniquely excluded from appearances. Then, when the filter is updated, the appearance will be recreated, and the atom marked as "dirty". After it has been updated, the SendMaps() function (sometimes also called maptick), which is a internal byond function that iterates over all objects in a clients view and in the clients.mob.contents, checks for "dirty" atoms, then resends any "dirty" appearances to clients as needed and unmarks them as dirty. This function is notoriosly slow, but we can see it's tick usage through the world.map_cpu var. We can also avoid more complex checks checking whether an object is visible on a clients screen by using the TILE_BOUND appearance flag.
 
-Finally, we arrive at clientside behavior, where we have two main clientside functions: GetMapIcons, and Render. GetMapIcons is repsonsible for actual rendering calculations on the clientside, such as "Group Icons and Set bounds", which performs clientside calculations for transform matrixes. Note that particles here are handled in a seperate thread and are not diplayed in the clientside profiler. Render handles the actual drawing of the screen.

 For debugging rendering issues its reccomended you do two things:
 A) Talk to someone who has inside knowledge(like lummox) about it, most of this is undocumented and bugs often
