Tempo Editor

Hi All,

I've just completed a first implementation of a graphical tempo editor
for blue, allowing the user to edit tempo by using a line editor that
is placed above the timebar when made visible.

So far, my changeLog note is:

    [new] - Tempo Editor - allows graphical editing of tempo on timeline for
            root polyObject; clicking "Use Tempo" checkbox will enable use of
            tempo line and clicking of down arrow will show the tempo for
            editing or collapse it to reduce screen space usage; if enabled,
            will generate a Csound t-statement to control global tempo; older
            project which manually added t-statements in global orc will run
            correctly as tempo editor is not enabled by default; right-clicking
            on tempo line area when in edit mode will allow option to edit
            point values by table or to set the min/max bpm for the tempo line
            with option to truncate or rescale line point values for new min/max


If anyone has a chance to test from CVS, that'd be great.

Otherwise, I think also that there are issues with running csound and
getting the current tempo.  Is this true?  If so, I think I can create
a blue meta-opcode, something like:

kval blueTempo

that will return the current tempo for the score.  Does that sound
useful for tempo-synced effects, etc.?

Thanks!
steven
