GetLayerAngle
From Spheriki
Returns the angle about which a layer has been rotated.

Usage
number GetLayerAngle(layer);
- layer Number, non-negative. The index of the layer to query.
- number is returned, the value of which is measured in radians anticlockwise.

Examples
The following example assumes there are at least three layers on whatever map is being used.
SetLayerAngle(2, Math.PI * 0.5); var bleh = GetLayerAngle(2);
This sets the angle of layer 2 of the current map to 90 degrees anticlockwise (or pi / 2 radians), which is equivalent to turning it on it's left side. Then that value is grabbed out again and placed into the variable bleh.

Notes
- Naturally, this function only makes sense in the context of map engine execution. That is, the map engine should be running before you call this.
- Like all functions that deal with angles, this function operates in radians. Conversion between degrees and radians is trivial.
- The angle of rotation of a layer can be set using SetLayerAngle().
