#41 Rendering bug with Wedge spanning one note

[Arshia Cont]

Render the following snippet and observe the superposition of Wedges:

{ [ \staff<1>  
\clef<"g2"> \key<1> \meter<"2/4", autoBarlines="off", autoMeasuresNum="page"> 
\crescBegin<autopos="on", dy=4.8hs> \stemsUp \slurBegin:1<curve="down"> \beam( d/8 \crescEnd 
\dimBegin<autopos="on", dy=4.8hs> f#/8 d/8) \slurEnd:1 \grace( \beamsOff b/8) \dimEnd \beamsOff  a/8  \bar 
] }

After some tests, it seems like the bug is related to cresc and dim having one note between their Begin/End spans. If there are two notes inside each Begin/End, it will disappear.

Note that such situations appear very frequently when converting MusicXML especially when wedges appear right after another (like the example here taken from a Schumann Romance).

Fixed.
