accidently left alwaysBlend global defaul set to true during development. Looking forward to our new org based repo where I'll be constrained more than my current wild-west repo, sorry. corrections also to pan constrainment details which came to the forefront while working on collections zoom and panconstraints. Added new ui feature page to demo basics.
