+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+#
+# Usage:
+#   generate_product_version(
+#     SomeOutputResourceVariable
+#     NAME MyGreatProject
+#     ICON ${PATH_TO_APP_ICON}
+#     VERSION_MAJOR 2

+#     VERSION_REVISION ${BUILD_REVISION}
+#   )
+# where BUILD_COUNTER and BUILD_REVISION could be values from your CI server.
+#
+# You can use generated resource for your executable targets:
+#   add_executable(target-name ${target-files} ${SomeOutputResourceVariable})
+#
+# You can specify resource strings in arguments:
+#   NAME               - name of executable (no defaults, ex: Microsoft Word)
+#   BUNDLE             - bundle (${NAME} is default, ex: Microsoft Office)
+#   USE_ICON           - flag that shows whether icon is used or not
+#   ICON               - path to application icon (${CMAKE_SOURCE_DIR}/product.ico by default)
+#   VERSION_MAJOR      - 1 is default
+#   VERSION_MINOR      - 0 is default
+#   VERSION_PATCH      - 0 is default
+#   VERSION_REVISION   - 0 is default
+#   COMPANY_NAME       - your company name (no defaults)
+#   COMPANY_COPYRIGHT  - ${COMPANY_NAME} (C) Copyright ${CURRENT_YEAR} is default

+
+Color2DSlider
+-------------
+![Color2DSlider](Color2DSlider.png)
+
+This widget allow the user to select 2 HSV color components at the same time,
+by default that is Saturation and Value but they can be changed.
+
+ColorDialog
+-----------
+![ColorDialog](ColorDialog.png)
+
+This is a dialog analogous to <tt>QColorDialog</tt> but with a much nicer and friendlier 
+user interface. It uses several of the other widgets.
+
+ColorLineEdit
+-------------
+![ColorLineEdit](ColorLineEdit.png)
+![ColorLineEdit with color preview](ColorLineEdit_with_color.png)
+
+This is a <tt>QLineEdit</tt> intended to be used to edit and display color names.
+It accepts several string formats:
+* <tt>#f00</tt> (3 hexadecimal rgb digits)
+* <tt>#ff0000</tt> (6 hexadecimal rgb digits)
+* <tt>rgb(255,0,0)</tt> (function-like)
+* <tt>red</tt> (color name)
+
+It can optionally display the color it represents on its background.
+
+ColorListWidget
+---------------
+![ColorListWidget](ColorListWidget.png)
+
+It allows to display and edit a list of colors.
+
+ColorPaletteWidget and Swatch
+-----------------------------
+These widgets handle color palettes.
+
+![Swatch](Swatch.png)
+
+**Swatch** only handles a single palette, can be used to just select colors from the 
+palette or to modify the palette via drag and drop operations.
+
+**ColorPaletteModel** is a list model that represents palettes with can be used
+with the Qt item view widgets, it provides a name and a preview icon for
+each of the stored palettes.
+It also has functionality to load and save palettes from the filesystem.
+
+![Read-only ColorPaletteWidget](ColorPaletteWidget_readonly.png)
+![ColorPaletteWidget](ColorPaletteWidget.png)
+
+**ColorPaletteWidget** manages a list of palettes (via **ColorPaletteModel**).
+Has two modes: read-only only allows to select palettes and colors,
+otherwise it can be used to modify the list of palettes and the palette itself.
+
+ColorPreview and ColorSelector
+------------------------------
+![ColorPreview](ColorPreview.png)
+
+**ColorPreview** is a widget that displays a color or compares two colors.
+
+**ColorSelector** is like **ColorPreview** but when clicked it shows a ColorDialog.
+
+GradientSlider and HueSlider
+----------------------------
+![HueSlider](HueSlider.png)
+
+**GradientSlider** is a <tt>QSlider</tt> which uses a gradient as its background.
+
+**HueSlider** is specifically made to select a hue and has more information
+about the represented color.
+
+
+GradientEditor
+--------------
+![GradientEditor](GradientEditor.png)
+
+**GradientEditor** is similar in appearance to **GradientSlider** but it's for editing the gradient.
+
+
+GradientListModel and GradientDelegate
+--------------------------------------
+![GradientListModel](GradientListModel_combo.png)
+![GradientListModel](GradientListModel_view.png)
+
+**GradientListModel** is a <tt>QAbstractListModel</tt> used to list gradients (useful for combo boxes, item views and the like).
+
+**GradientDelegate** is an item delegate to edit gradients in an item view.
