[Pythoncad-developer] Some small points

[<ger...@gm...>]

Hi Matteo,

A have some small points to discuss.

1) In the repository there is a gtkError.py and a gtkerror.py  
(http://pythoncad.git.sourceforge.net/git/gitweb.cgi?p=pythoncad/pythoncad;a=tree;f=PythonCAD/Interface/Gtk;h=f0c84bcb2e94d8ff2a1229d922f96399bbb2cc30;hb=R38).
On windows this can give problems, maybe it is better to give all the  
source files lower case filenames.

2) Angles are internally measured in degrees, I think that this should be  
radians.
All the math/cairo functions take radians as input parameters, maintaining  
degrees as internal values causes constant calculation from degrees to  
radians.
If we maintain radians as the internal value only in the user interface a  
translation has to be done.

3) Sometimes points are defined as a tuple of two doubles and sometimes as  
a Point (object).
This also leads to unnecessary conversions between the two.
For me I think alway use the Point object for point is the most convenient.
The point object contains functions for distance, equality etc. which are  
handy.
