Turn prerendered cutscene into Ingame-Engine cutscenes

This are some reworked w2.scene files for modders to import in own mod projects.

With this files the cutscenes are not longer playing as pre-rendered videos. The cutscenes are directly rendered ingame in the engine (Info: the kaer morhen intro cutscene cannot be played in the game engine).

This ist a proof-of-concept and has some glitches, like some stuttering on camera changes.

I'm too lazy too build a mod now. So only the w2.scene files for using in own mods this time. Have fun.

The following cutscenes are turned from pre-rendered videos into realtime ingame engine cutscenes:

- White orchard / yennefer and nilfgaardian patrol / wild hunt attack

- Kaer Morhen battle / Ciris voice-explosion

- Before final battle / nagflar arriving

- Final battle / Ciri meets Wild Hunt mage

- Last Game sequence / Ciri walks into tower / Walks trough blizzard

If you want to complete this, here is a very short tutorial:

As an example use the original quests\part_3\quest_files\q501_eredin\scenes\q501_02a_nalgfar_arrives.w2scene:

Look at index 1 (CStorySceneVideoSection #2): This ist the prerendered cutscene.

We want to change this into the Engine-Cutscene. But where ist the

Engine-Cutscene? Answer: We have to look trough the entire indices for

an entry with an cutscene-template. Afters some searching this must be

index 6 (CstoryCutsceneSection #7).

No we delete the "...usm" variable in index 1. Therefore the Prerendered scene not longer playes.

Then (still in Index 1) we set the variable "nextLinkedElement" from

"CStorySceneOutput #4" to the Engine-Cutscene, we've found

(CstoryCutsceneSection #7)

Finally in the Engine-Cutscene (Index 6) we have to create a new "nextLinkedElement" variable and point this to

"CStorySceneOutput #4"

In other files it may get somewhat complicated, because the Engine-Cutscenes aren't easy found.

But the principle remains the same.
