only driver compiles remove accel-base types merge linear + classic move gain cap logic into classic impl, cap is now set in terms of output use cap/limit to determine negation remove weight, add replacement for power mode only remove legacy offset option remove naturalgain mode add legacy mode flag naturalgain -> natural natural -> natural + legacy flag add dpi setting and more accel args + defaults (prep for ips mode) replace output speed cap with input cap
