I removed the range limitation completely so now the index is a full 32 bits. I don't think there is much reason to limit it to 256 or to any other number less than 2^32 unless there is a threshold over which we can definitely discern that a user is making a mistake. Even with the range opened up, Ada still checks the type, Plot_Color_Type. I chose to limit the range in the bindings to 0..255 since that corresponds to 24 bits total for r, g, and b and is more than adequate to handle example 2. Not sure I understand, since 256 is the number of map entries, not the bits per color. Jerry Jerry, please review and correct any strange things I did in Ada for x02a.adb. Done (nothing strange).

Re: [Plplot-devel] Cookbook for implementing the remaining Ada examples
Here is a little list that should help with the state of the Ada examples. I expect to do most of them but if anyone wants to jump in don't be shy 8^).

For example, I am currently working on x02a.adb. Which is now done. It took a bit of thrashing around (I didn't realize Ada rounded when converting from floating point to integer) to get exact agreement with the result for example 2 created with the C implementation, but eventually I got there.
