[GSAS-II] More GRAS-2 problems on linux

[Lambert van Eijck - TNW]

Dear Anselm,

this works for me:

   Python:     3.7.7
   wx:         4.0.4
   matplotlib: 3.3.1
   numpy:      1.19.1
   scipy:      1.5.2
   OpenGL:     3.1.1a1
   Image:      7.2.0 (PIL or Pillow)
   Platform:   linux 64bit x86_64
   Max threads:2
This is GSAS-II revision 4593 (SVN version 4593)

As I understand it, it is mostly the Wx part that can cause problems. In 
my case, typically buttons are too small whereby you have to guess what 
the text inside a button or a menu is (sometimes). I am using debian 
(very similar to ubuntu)

best regards, Lambert
