We should be pairing gtk_window_get_size with
gtk_window_set_default_size to avoid inconsistencies between the size
reading and setting code. eg., in recent GTK+ versions,
gtk_window_get_size and gtk_widget_set_size_request differ in their
interpretation of the CSD chrome.
However, gtk_window_set_default_size didn't work with non-resizable
GtkWindows, until now.

Tablets have not always an eraser (most of the generic tablets like Huion,
UC-Logic, etc... don't). We should not reject such tablets.
Commit 54849a9 (wacom: Only the stylus and eraser tools need to exist)
mentioned that we were not sure about eraser, and I think we should not
assume one either.
To do so, we simply ignore the eraser xinput node and rely on
libwacom to actually provide the eraser information.
If the stylus does not have the eraser tip, we may fall in the
LAYOUT_OTHER case. We have a picture of a generic Wacom pen with an
eraser, and the leaders linking the widget to the picture are scrambled.
To prevent that, gray out the eraser pressure slider so that we do not
break the layout.

Since GTK+ commit 05b1ea84b, this hint is used in GtkNotebook to add
a GTK_STYLE_CLASS_FRAME when rendering the notebook frame, so the theme
renders those frame-alike. As it's not what we want for the wacom panel,
set show-border to FALSE on all GtkNotebooks.

The name of the file was also changed to calibratorgui.c/h to avoid
it being inconsistent, this way it is no longer dependent on the
the technology.
