Maestro - Base Map Scale Ranges

[crispinatime]

Hi,

A couple of minor edits to scale ranges to catch unexpected behaviour:

1) When using the "Generate" button and the 'Exponential' method the scale ranges start at the 'Min Scale' but do not end at the 'Max Scale' - if I set a max I expect that to be preserved. I think the "Number of Scales" is generating but missing the top end max scale which is not added in again as it would make numscales +1

2) When manually editing a 'Display Scale' list and saving the list the Map is not invalidated (*) so it is easy to close and loose changes

3) It maybe just me but unless I run full-screen I cannot see the 'Generate' button, the scaling/position of the controls seems not to update if you shrink a window

Items 2) and 3) resolved with r6491 and r6492
