#46 Overlay multiple segmentations

[Ma Da]

Hi, the function to overlay multiple images is really neat. Is it possible to implement the same functionality for label segmentations as well, so that user can load multiple segmented labels, and overlay them together with transparency?

Currently, the user can only switch segmentation layers by pressing the keyboard shortcut { and }, but cannot overlay them together. This functionality will be very useful if people have multiple labels for the same subject. For example, having a semi-transparent brainmask/tissue-segmentation displayed on a brain MRI image would be very helpful when drawing the internal brain structure labels, and make sure the manual labels are within the anatomically-correct boundary.

I've attached a potential GUI layout to arrange the additional segmentation layer layout in the empty space at the left of the display window.

Has this function being added yet? I use a lot manual segmentation and I would like to overlay images from the same subject being manual segmented by different examiners. Is that possible yet? Thank you
