Errors

The policy for the DlangGraphicsWG about errors is the following:

1. Internal functions may use any mechanism, left at the discretion of the implementer

2. In the public parts of the library that have to follow -betterC (TBD):

• If the function is publicly exported by a module and has to report an error message, use Result!T a combination of a T an a message string. If the message string is null then the T is valid.

• Else if the function doesn't have to report an error message, use error codes (bool return and out params).

3. In the parts of the library that don't have to follow -betterC (TBD)

Use normal D exceptions.
