* Allow <orientation> and <color> to work on group references
* Fix some corner cases where group bounds could be miscalculated
* Fix a corner case where MAME could incorrectly refuse to instantiate groups
* Add more checks to complay.py
* Document more of the layout format
* Clean up some corner cases in layouts with repeating blocks
* Make complay.py validate many more elements and attributes
* Make complay.py easier to use for just validating a layout
* Remove redundant view from Sega VMU layout
* Make buttons visually respond to input in whousetc.lay
* Add view with LED displays as well as terminal for aim65_40 and use repeats
* Clean up some outdated "game" terminology in clifront.cpp
* Initiaise a couple of members in tap/tun network module
* Start documenting layout format
Input and screen tags are now resolved relative to a layout's owner
device.
Easy way to demonstrate is with: mame64 intlc440 -tty ie15
Previously you'd only get the IE15 terminal's layout and you'd be unable
to use the INTELLEC 4/40 front panel. Now you'll get the choice of
layouts from both the system and the terminal device in video options.
appropriate containers, remove misleading const qualifiers, reduce
repeated XML walking.
(nw) Groups aren't parameterised, so they aren't as useful as they could
be (yes, it's on my TODO list). However, it's already useful for
putting a common set of elements in multiple views, potentially at
different locations/scales. See intlc44.lay and intlc440.lay for
examples of the level of copypasta this can eliminate. Be aware that
groups with explicit bounds don't clip thair content, it's only used for
calucating the transform matrix.
Use standard uint64_t, uint32_t, uint16_t or uint8_t instead of UINT64, UINT32, UINT16 or UINT8
also use standard int64_t, int32_t, int16_t or int8_t instead of INT64, INT32, INT16 or INT8
