photoQuad version 1_4 (02-Apr-2016)
-----------------------------------
If the "launch random points lasso" button was pressed while another
lasso tool session was already running, the tool would hang, making 
the whole photoQuad software unresponsive. This update solves this 
problem, and also fixes similar (double-launching) bugs in all other
photoQuad tools.

In the "Save layers as.." window, if the custom filename entered by
the user contained a dot ".", the default ".Layer.pqd" file extension 
was erroneously omitted. For example, a layer filename "mylayers.foo" 
>> was saved as: "mylayers.foo" 
>> instead of the correct: "mylayers.foo.Layer.pqd"
This prevented the layer file from being loaded back to photoQuad,
unless the file extension ".Layer.pqd" was added by the user by manually
renaming the file on disk.
The same problem applied to all CSV exports of the various analysis 
tools (e.g. a species regions descriptor file "foo" was properly saved
as "foo.sppregions.csv", but a file "foo.bar" was saved as "foo.bar",
i.e. the ".sppregions.csv" was erroneously omitted).
This update fixes these bugs.


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 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.
