lyx_mirror/src/graphics/GraphicsParams.cpp
Abdelrazak Younes 4a1be58591 - Simplify prefs, graphics and external display options which are now true or false.
- the display combo in the prefs, external and graphics dialogs are gone
- the lyxrc display_graphics option now overrides any local inset display option
- The external template format has a new tag: Preview
- format incremented to 337
