Gem support: "Gem has been compiled without GLU - disabled pix resizing"

[jamshark70]

I have a pd/gem patch that works perfectly with standard Pd.

Running the same patch in plugdata (v0.9.2), I get two extra messages in the console window that don't appear in Pd:

// upon load:
gemmouse: no method for 'saved'

// after starting rendering
Gem has been compiled without GLU - disabled pix resizing

The gemmouse message doesn't seem to affect anything (but it's just odd that it doesn't happen in Pd -- and there is no input to this object in the patch).

The GLU message breaks rendering -- because pixes aren't getting resized, compositing operations don't work. However, a minimal example with pix_resize doesn't show the error.

Also plugdata + gem causes audio rendering in SuperCollider to become choppy, even if plugdata's DSP is turned off.

I'm loading the same Gem libraries in both environments -- both ~/Documents/Pd/externals/Gem and ~/Documents/plugdata/Externals/Gem symlink to the same /usr/local/lib/pd/extra/Gem. (Had to build myself for xxf86vm support.)

Not critical because I can just use Pd, but I was hoping to use plugdata's improved UI for patch development.
