SRID Ignored during client operations - example code does not set projected SRID causing inverse projection to do nothing

Hi,

Basically all in the title, but for clarity a description.

The `seattle` and `redmond` points are projected to **SRID 2855**.
However, the transformation does not update a geometry's **SRID**, leaving it as **4326**.
Trying to project **2855** back to **4326** doesn't do anything because the `CreateTransformation` method is receiving **4326** as argument for both parameters.

An updated sample that rectifies this minor issue might be helpful for any future user.

Thanks!
