photoQuad version 1_3 (24-Sep-2015)
-----------------------------------
This update fixes a regression introduced in photoQuad v1_1. 
When a ROI created with segmentation contained no pocket regions,
there was no way to assign that ROI to a species region. From
the user's perspective, right-clicking the ROI did not spawn the
"Assign to species" popup, effectively rendering the entire 
segmentation toolbox unusable.
This bug only affected photoQuad versions v1_1 and v1_2, and was
not present in the initial release v1.0.


photoQuad version 1_2 (23-Sep-2015)
-----------------------------------
Fixes a bug that that only appeared on Windows 8/8.1/10 machines,
and was not properly resolved in revision v1_1. photoQuad would
crash whenever a window was closed with a "click-and-close" 
behavior, i.e. when there was no "OK" button to graciously close 
the window. This affected the custom color selector popup tool, 
and the "About photoQuad" window.


photoQuad version 1_1 (20-Sep-2015)
-----------------------------------
Fixes a severe bug that resulted to a runtime error when
loading a saved layer file that contained regions created
with segmentation. If regions contained pocket regions, 
loading the layer would error-out. This version fixes this
problem, and is backwards-compatible, i.e. an old layer 
file that failed to load will now be properly imported.

Fixes a bug where photoQuad would erroneously deny to load a
saved layer because an object "has coordinates that exceed the
image dimensions". This was due to round-off errors in regions
that were drawn close to the image edge. This version fixes 
this problem, and is backwards-compatible, i.e. an old layer 
file that failed to load will now be properly imported to photoQuad.

Fixes a bug that resulted to a rare, runtime error when drawing
regions. Due to pixel round-off errors, drawing a very small 
outline could result to a zero-pixel region. If this happened, 
analysis could not continue, and if the layer was saved, it 
would fail to load again.

Fixes a bug where photoQuad would crash when a color was selected
from the custom color selector popup. This was only observed on 
Windows 8/8.1/10 machines.
