[jitter] Re: Re: v001 Shaders Beta 2

Hi vade,

doesn't work for me neither on a powerbook G4 PPC Mac OS 10.4.10 Max/MSP 
4.6.3 & Jitter 1.6.3. ATI Mobility Radeon 9700 64mo

pretty cool on an imac intel ATI Radeon HD 2600 Pro

I have got the following errors (with the lumaglyph help patch) but on 
the imac too so it might not be related :
• error: jit.gl.shader: unable to bind GLSL uniform param: 'amount'
• error: jit.gl.shader: unable to bind GLSL uniform param: 'glyph'

anyway, thanks for sharing this !
