Make weapons panel automatically disappear

Make weapons panel automatically disappear
hud_panel_weapons_timeout "10" "panel disappears if you don't switch weapon for this amount of seconds"
hud_panel_weapons_timeout_effect "1" "disappearance effect: 0) no effect; 1) panel moves out of screen; 2) panel fades out"

Note: I had to use panel_pos and panel_size instead of pos and mySize to make properly work HUD_Panel_DrawBg(1);. Actually, it's even a good thing as pos and mySize aren't really needed... (like in every other panel, btw).
