So that we can erase the progress bar after we're done with it, avoiding
things like:
-------------------------------------------------------------------
┌─Error:──────────────────────────────────────────────────────┐
│Can't annotate unmapped_area_topdown: │
│ │
│No vmlinux file with build id a826726b5ddacfab1f0bade868f1a79│
│was found in the path. │
│ │
│Note that annotation using /proc/kcore requires CAP_SYS_RAWIO│
┌Processin│ │──┐
│ │Please use: │ │
└─────────│ │──┘
│ perf buildid-cache -vu vmlinux │
│ │
│or: │
│ │
│ --vmlinux vmlinux │
│ │
│ │
│Press any key... │
└─────────────────────────────────────────────────────────────┘
Can't annotate unmapped_area_topdown:
-------------------------------------------------------------------
I.e. that finished progress bar behind the error window. It is not a
problem when we end up redrawing the whole screen, but its ugly when
we present such error windows, provide a TUI method so that code like
the above may avoid this situation, as will be done with the annotation
code in the next cset.
