Get the newest version from http://www.expyriment.org/getit


New Features:
- new stimuli.Circle class
- new stimuli.Ellipse class
- new stimuli.extra.PolygonDot class
- new stimuli.extra.PolygonEllipse class
- new stimuli.extra.PolygonRectangle class
- new method: stimuli.Shape.add_vertices to add multiple vertices at once
- an additional suffix for the main data and event files can be set when
  creating an Experiment
- Unfilled Shapes by setting a line_width, when creating a shape
- Shape: new property line_width

Fixed:
- stimuli.Shape: several fixes, related to surface creation and xy point
  calculation
- Logging of unicode text in TextLine stimulus
- stimuli.TextLine and stimuli.TextBox can now also receive a font file as
  text_font argument
- stimuli.TextLine.copy()
- Bug fixes in self tester of stimuli
- Fixed segmentation fault when repeatedly initalizing and ending an experiment
- Fixed surface size shapes
- Fixed incorrect line_width plotting for scaled shapes
- Copying preloaded stimuli in OpenGL mode
- Bug fixed in io.InputFile.get_line()

Changed:
- io.DataFile: variable "Subject" is now called "subject_id"
- io.Screen.update() should be even more accurate now (about 0.5 milliseconds)
- misc.data_preprocessing: argument and property "experiment_name" in all
  objects is now called "file_name"
- misc.data_preprocessing.Aggregator can handle files with different suffixes:
  see __inti__ and reset
- stimuli.Dot: is_center_inside, is_overlapping and is_inside are deprecated now
- stimuli.Dot is deprecated now, use stimuli.Circle instead
- stimuli.Shape: is_point_inside and is_shape_overlapping are deprecated now
- stimuli.Shape.native_scaling does now optionally scale also the line_width
- stimuli.Frame: property line_width is now renmes to frame_line_width. Since
  line_width is a property the underlying shape and always 0 (filled shapes)
- stimuli.Frame is deprecated now, use stimuli.Rectangle with line_width > 0
- stimuli.Rectangle was rewritten and is not inherited from Shape anymore;
  the old Rectangle stimulus is now knwon as stimuli.extras.PolygonRectangle
