* would cause out-of-bounds array accesses in Layer.lookup(),
|

* Layer.updateLiveCompositeKeymap(), etc.
|

* Note that many INJECTED keypresses use the UNKNOWN_KEYSWITCH_LOCATION macro

* which gives us row==255, col==255 here. Therefore, it's legitimate that
|
|
* we may have keypresses with out-of-bounds (row, col).

|
* However, some INJECTED keypresses do have valid (row, col) if they are
|
|
* injecting an event tied to a physical keyswitch - and we want them to go
|
|
* through this lookup.
|
|
* So we can't just test for INJECTED here, we need to test the row and col
|
|
* directly.
|
|
* Note also that this (row, col) test avoids out-of-bounds accesses in *core*,
|
|
* but doesn't guarantee anything about event handlers - event handlers may
|
|
* still receive out-of-bounds (row, col), and handling that properly is on
|
|
