Algorithm parameter dialogs have unnecessary buttons on the title bar

[Keith Brown]

As everyone knows, when launching an algorithm we are presented with a dialog to enter our parameters. This dialog seems to have some useless buttons on the title bar.

On Windows, this dialog has a redundant '?' or 'What's this?' icon on the title bar, as instead of showing the 'cursor and question mark' icon to examine a field, the 'unavailable' cursor shows and nothing is a valid target.

On Linux, this dialog has a maximize icon and can be snapped to the sides of the screen. I was under the impression that this dialog shouldn't be resizeable. (also note that on windows this dialog is horizontally resizeable)

Evaluate these buttons' usefulness and remove if deemed unnecessary.

if the dialog should be a fixed size, make it that way.
