Moved it all back; the preemptive multitaksing during an event handler kills us on all platforms. Going to have to restrict ALL GUI accss to happening from one t hread, so going to need to drop uitask entirely and have just a start() callback for startup code and a post() function for posting requests to windows (like channel sends but into a perpetual buffer).

-// A ProgressBar is a horizontal rectangle that fills up from left to right to indicate the progress of a long-running task.
-// This progress is represented by an integer within the range [0,100], representing a percentage.
-// Alternatively, a progressbar can show an animation indicating that progress is being made but how much is indeterminate.
-// Newly-created ProgressBars default to showing 0% progress.

-// If percent is in the range [0,100], the progressBar shows that much percent complete.
-// If percent is -1, the ProgressBar is made indeterminate.

-// Calling SetProgress(-1) repeatedly will neither leave indeterminate mode nor stop any animation involved in indeterminate mode indefinitely; any other side-effect of doing so is implementation-defined.
