* Plumebd with data transfer

* Getting mainpage to talk to getbitmap.  moving share callbacks from mainpage to graphingcalculator

* Trying to get bitmap from renderer.

* work

* Share worked

* cleanups

* Cleanups progressing

* Share working, need loc for title string and user notification incase of a failure.  Then add the equations key.

* More cleanup, now using share icon image and resources for strings.  Still need to do the graph equation key.

* Change share to html based start.

* Key working, with UL but going to try changing to table.

* Fix a html formating error, generating a new UL for each equation.

* Switched over to a table for equation key and have color block formating

* Updates from PR feedback, using Graphing::IBitmap abstraction.

* Update src/Calculator/Views/GraphingCalculator/GraphingCalculator.xaml.h

* PR Updates.

* Add variables to the graph key.

* eod

* Passive graph value tracing working.

* Basic active tracing cursor working.

* Move active tracing from graphingcalculator to grapher to save some hops.
Also block tracking of the active tracing key's when in the EquationTextBox.

* Active tracing working, need to put button on screen for activation.

* Added active tracing control button (placeholder image)

* Eod

* Popup trace value now tracks the highlighted point.

* Popup skined

* PR Updates.

* Update certificate thumbnail so VS2019 doesn't have a build error.

* PR Updates, change tracing value to use tooltip static resource so we automatically change depending on system values.  And changed text formatting of the value to be generic (x,y) value.

* PR updates, changed how we detect who has focus so we don't eat keys when not in active tracing.

* Additional filtering for the Key Up/Down in the grapher.
