SWT needs to expose some way to compute the height of a control given its width
(and visa versa). 

Control.computeSize does not behave as documented. It takes the inner content
size (the size of the control minus trim) as hints, not the actual control size.
SWT does not provide API to compute the trim size of a control given its outer
dimensions, and layouts only have knowledge of the outer dimensions of child
controls.

This enhancement asks for one of the following:

1. Change the implementation of computeSize to match its JavaDoc and the way it
is being used in Eclipse.
2. Provide a new method whose behavior matches the JavaDoc for computeSize.
3. Provide a new method that returns a control's trim given its outer dimensions.

Personally, I would prefer option 1. This would simplify code within SWT, and
would fix downstream bugs in apps that expect computeSize to behave as
documented. Options 2 or 3 would require updating the JavaDoc for computeSize to
describe the actual behavior of computeSize.

This is required in order for ANY layout to correctly handle wrapping text.
