that animated icons can be done with it. - Changed FImageCollection to use a TArray to hold its data. - Fixed: SetChanHeadSettings did an assignment instead of comparing the channel ID witg CHAN_CEILING. - Changed sound sequence names for animated doors to FNames. - Automatically fixed: DCeiling didn't properly serialize its texture id. - Replaced integers as texture ID representation with a specific new type to track down all potentially incorrect uses and remaining WORDs used for texture IDs so that more than 32767 or 65535 textures can be defined.

// DESCRIPTION:
|
|
// Sky rendering. The DOOM sky is a texture map like any
|
|
// wall, wrapping around. 1024 columns equal 360 degrees.
|
|
// The default sky map is 256 columns and repeats 4 times
|
|
// on a 320 screen.
|
|
//
|
|
//

// Needed for FRACUNIT.
