- changing the configuration for generating files
- preparing to use a PDF library to display Equations (poppler-qt or
mupdf)

- Modified RenderEngine to do check for the latex errors and stop if
errors are found.
- Modified EquationItem to clear if no image is available. Equation item
now shows a grab cursor (hand) if it is possible to drag it, normal
cursor otherwise
- Modified Mainwindow and Equation item in order to not be possible to
drag empty equation
- Mainwindow shows a busy cursor while the RenderEngine is running

- Modified RenderEngine to not take care of latex exitcode. This is
required so that we parse and display the latex errors in mainwindow
- changed preloader image with a nicer one
- Functional preview of the generated image PNG

22. By Mihai Niculescu on 2013-05-23

* Fixed RenderEngine
* Added a nice preloader to show instead of the equation while the
RenderEngine generates the files
- cleaned up some obsolete and unused code in MainWindow

21. By Mihai Niculescu on 2013-05-23

* Implemented a RenderEngine class to deal with the rendering and
programs execution

20. By Mihai Niculescu on 2013-05-22

- solved bug for find and highlight when dealing with transparent
background color. If color is transparent than highlight in white.
- fixed WidgetColorPicker.h to show real swatch transparent color.
- fixed custom color selection in WidgetColorPicker
- Modified foreground color combobox to not show transparent option
(latex can not render transparent color)

19. By Mihai Niculescu on 2013-05-22

* Added more environments: display, inline(which were before) and align
and text. Select them from the Mainwindow and Preferences
* modified UI mainwindow and polished it for better smaller layout
* removed Latex log output and tabs from mainwindow. There is no need
since the error parser is enough

equation editor
- corrected UpdateEquation and UpdateImage to call runCommand().
Preparing to run the commands in a separete thread

17. By Mihai Niculescu on 2013-05-21

* Added a check for the requirements (latex, dvipng,etc)
- commands paths in Preferences Dialog are now readonly. They can be
changed only though the "Change" buttons
- Change buttons for the commands select only the specific executables
(filters other files)
