Subject: Store annotations as objects emplaced in the vector
X-Git-Tag: pulseview-0.2.0~182
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=db62bbfda512aeddca5b9d7b5960e9cf24b8859c;p=pulseview.git

Store annotations as objects emplaced in the vector

Rather than as pointers to heap allocated objects.
