bug: event behaving differently between ginga and gingagui

[RodrigoDornelles]

I made an example application to try to understand why released was coming before press and I realized that there is an inconsistency between the two binaries. (both compiled from the same commit)

• feat: add example dump events #189
• Key pressing event swapped #173

ginga	gingagui

ginga (wrong)

label, class=ncl, type=presentation, action=start Key=CURSOR_DOWN, class=key, type=release key=CURSOR_DOWN, class=key, type=release keỷ=CURSOR_DOWN, class=key, type=release key=CURSOR DOWN, class=key, type=release key=CURSOR DOWN, class=key, type=release key=CURSOR-DOWN, class=key, type-release Key= CURSOR DOWN, class=key, type release key=CURSOR_DOWN, class=key, type=release key=CURSOR_DOWN, class=key, type=release key=CURSOR_DOWN, class=key, type=release key=CURSOR_DOWN, class=key, type=release key=CURSOR_DOWN, class=key, type=release key=CURSOR_DOWN, class=key, type=release key=CURSOR_DOWN, class=key, type=press key=CONTROL L, class=key, type=release key=CONTROL_L, class=key, type=press

gingagui (correct)
