Subject: Adds convert-ly rules for the Flag grob.
X-Git-Tag: release/2.15.14-1~18^2~6
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=9e781a447d4ea0dc072403b4c7f0b176f2edb2e2;p=lilypond.git

Adds convert-ly rules for the Flag grob.

All Stem properties that are moved to Flag are now changed to Flag
properties.  Additionally, Stem grobs' being overriden and reverted
to and from transparent triggers the same overrides and reverts with
Flags.
