• Bug fix
• New feature

Description

After migrating to SDL inputs, we were checking for modifier keys like this:

boolean control = SystemUtils.IS_OS_MAC 
? input.modifiers() == InputConstants.MOD_SUPER 
: input.modifiers() == InputConstants.MOD_CONTROL;

to determine whether control is pressed. This wouldn't work because the input constants for modifiers are masks that you compare against the actual pressed modifiers:

MOD_SHIFT   =   0000 0000 0011 (3)
MOD_CONTROL =   0000 1100 0000 (192)
MOD_ALT     =   0011 0000 0000 (768)
MOD_SUPER   =   1100 0000 0000 (3072)

whereas the current modifiers found in a KeyEvent might look like this:

// Right control is pressed, left is not
event.modifiers() = 0000 1000 0000

Added Input#modsMatch(int currentMods, int... desiredMods) to mimic previous logic, it checks if the current modifiers contains only the desired ones, nothing else.
