1. Binary alternatives to some commands which take a camera as the LHS arg:
worldToScreen:
```
cam worldToScreen posAGL (or posASL, which I prefer)
```
screenToWorld:
```
cam screenToWorld uiPos (returns AGL, or better, ASL)
```
positionCameraToWorld:
```
cam positionCameraToWorld relPos (returns AGL, or better, ASL)
```
2. A new scripting command: `screenToWorldVector`, (alt names: `posScreenToDirection`, `screenToDirection`).
It's similar to the first step of `screenToWorld`, i.e. it returns the direction vector that is needed for `screenToWorld` to do the intersection.
The reason I ask for this command is that `screenToWorld` tries to perform an intersection, which is both costly, and may return undesired result.
Unary version for the main camera:
```
posScreenToDirection uiPos
```
Binary version for any camera:
```
cam posScreenToDirection uiPos
```
