Make cursor.blinkCanceled public so that it can be handled #834
Description
Is your feature request related to a problem? Please describe.
I'm writing a tea.Model that wraps around a bubbles.textinput and a few other bubbles.
In my Update method, I have a switch statement on the msg.(type), in which I handle certain messages I send myself but forward for instance tea.KeyMsg to the inner textinput. I want to include a default case to that switch statement that panics, so that I ensure I don't accidentally forgot to handle a message type while developing.
Now the issue occurs when the inner textinput is Focus'd, because then cursor.blinkCanceled messages sometimes pass through the Update chain, which triggers the panic I have.
This wouldn't be a problem if I could simply have case cursor.blinkCanceled:, but since blinkCanceled is local to the cursor package the compiler won't let me catch it.
Describe the solution you'd like
type cursor.blinkCanceled... -> type cursor.BlinkCanceled... so that the type is exposed to the outside.
Describe alternatives you've considered
For now I've disabled blinking altogether on the inner textinput, but that feels like a shame!
Additional context
Update:
Actually, setting input.Cursor.Blink = false doesn't appear to prevent the blinkCanceled messages from being fired. Would there be another way to prevent these messages from being fired?
