Vector Properties dialog - Labels tab - several minor problems

[smizuno]

Vector Properties dialog - Labels tab - minor problems:

1. the Preview area does not show the current font and color settings on entering the dialog. This is confusing as it will change if the font dialog is canceled.

2. on entering the dialog, Buffer is the selected options panel, but is not indicated in the list. I believe that Font should be the selected one and be so indicated.

3. when the color buttons for Font or Buffer are used, if the Select Color dialog is Canceled the current color for the item changes to black.

4. on entry to the dialog, if the the Buffer labels? control is off, the Buffer size, Color, and Buffer size units controls are enabled. They should be disabled. Toggling Buffer labels? on, then off sets the controls' state as expected.

5. the Buffer Transparency control has no effect. It should be disabled if the feature is not currently available. This control is disabled initially, but is enabled after turning on label buffering.

6. How does the "Multiline labels?" control relate to buffering labels? It seems to me that this control should be placed somewhere else related to labels generally.

Tested with Windows and Linux.

#183 also mentioned, the label's orientation should be previewed.

Not sure if this is the place for my comment... Not disagreeing with this bug report. Want to comment that label buffer transparency would be an excellent feature and hope difficuties with implementation does not lead to it being dropped. Thank-you for your work !
