Import Gervill fixes from CVS. See CHANGES.txt:
6823446: Gervill SoftLowFrequencyOscillator fails when freq is
set to 0 cent or 8.1758 Hz.
6823445: Gervill SoftChannel/ResetAllControllers jtreg test
fails after portamento fix from last merge.
6821030: Merge OpenJDK Gervill with upstream sources, Q1CY2009
- Fix: Notes get stuck on when we overflow the synthesizer
with rapid note on /off messages.
JTreg test has been created:
test/com/sun/media/sound/SoftChannel/NoteOverFlowTest
- Fix: Portamento controller reset to wrong value in
SoftChannel.resetAllControllers.
This caused incorrect glider effect in some midi files.
For example in TuningApplet1 in TET-7 keyboard,
when note was pressed for first time a glider effect could be
heard.
- Fix: Delay modulation calculation in SoftChorus.LFODelay where
incorrect.
- Fix: Removed unnecessary volatile keywords in SoftChorus.
* fsg.sh: Don't remove (non-existing) com/sun/media/sound services.
* overlays/openjdk/jdk/src/share/classes/com/sun/media/sound/services:
removed.
