Explore showing multiline decorations

[usernamehw]

Try finding a space to fit as much text as possible (Tetris).

Whether it's a very long single line problem, or a multiline problem => find the best empty box to fit it (using multiple single line decorations).

---

• Highlight line where problem is from (since it's rendered in random position in the viewport)
• Closest problem multiline; doesn't calculate the best position properly atm
• Closest problem multiline by severity (error before warning)
• Closest problem multiline in viewport
• Align multiline message
• Split single-line long error into multiple lines
• Option to show multiple multiline error or an option to render as usual (all errors) if there are no multiline/long errors
• Show multiple problems from 1 line

hi! thanks for such a wonderful extension and including this on open-vsx too.

is this issue just about showing single but long diagnostic line or would also cover multiple diagnostic messages for same line??

e.g.:

Syntax error, insert "VariableDeclarators" to complete LocalVariableDeclaration [21:17]
Syntax error, insert ";" to complete LocalVariableDeclarationStatement [21:17]
