[Papervision3D] BitmapFileMaterial garbage collection

[Aaron Haines]

After tracking down the last issue to something unrelated to PV3D I am being
a bit more cautious this time, but I'm still seeing some memory issues with
Collada and BitmapFileMaterial

I have been testing the adding and removing of colladas, and when using
BitmapFileMaterial they don't seem to be garbage collected properly. The
memory taken up when the Collada is loaded is never released.

I'm using Papervision3D Beta 1.7 (20.08.07)
Flash CS3 - Flash Player 9

I have tested the same DAE using BitmapAssetMaterial and it's fine.
I also tried the same DAE with all the textures turned off and that was
fine, so it seems to be an issue with BitmapFileMaterial.

I'm still testing at the moment, so I won't jump to any conclusions.
Does anyone have any info related to this ?

Thanks
