Subject: * show anchor paragraph completely if the whole buffer is visible.
X-Git-Tag: 1.6.10~6444
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=bfd3a964b34977cba620b71ac2ccf651167e9648;p=features.git

* show anchor paragraph completely if the whole buffer is visible.

We need some better handling of the case when the cursor is in the
very first line, but the line is not completely visible. If the line
is not heigher than the BufferView we should scroll up to show it
completely.
