Modify my previous patch about zoom issues in eeschema (remove zoom limitations).

Also fix a minor zoom page issue in Libedit.
wxMSW, version 2.8.x must be patched.
Some zoom values smaller than 3 to 5 create artifacts on screen, mainly values < 1.
(corresponding to draw scale factor > 1 )

 * see http://trac.wxwidgets.org/ticket/9554
 
This is fixed in version 2.9.x
Workaround: ( that is not a full fix, but remaining artifacts are acceptable )

wxWidgets 2.9.1 (all platforms)
Has a problem when using the built in string to double conversion:
In countries using a comm instead of a point as floating number separator
after calling this conversion function, the comma is changed in point.
(Happens after reading a parameter stored in a wxConfig structure, if this
parameter is a double)
Workaround:
Use a version > 2.9.2
Currently ( 2011, april 12 ) the 2.9.2 is not yet finalized
(and can be found only on the wxWidgets snv server)
can be fixed by replacing the file <wxWidgets-2.9.1>/src/common/xlocale.cpp
by the corresponding file from the 2.9.2 version (from wxWidgets svn server)
