as far as feature requests go...

- frame limit should not be an arbitary power of 2, but would probably be
memory limited

- looping without pauses is important, and something that pix found
troublesome in his experiments with ogre >
http://libarynth.fo.am/cgi-bin/view/Libarynth/VideoTexture

- the ability to support diff. resolutions, and bitdepths, but not necesarily
manual rescaling.

- being able to use the same mapping as textures, ie wrapped or tiled.

- smooth sequential replacement of textures [prob. related to looping]

- layered textures? alpha, being able to use the gl blendmodes...

in most ways, i thinks the interface should follow that of img textures. the
'load' command could use optional args or keywords for things like looping,
framerate, etc+ the manupulation [eg. playback speed, sequencing] requires a
bit more thought, but ideally would be similar, eg.
(framerate video-texture 25) or just (framerate 25) for a grabbed object. .

(of course, there are a few edge cases, such as what happens when changing the
direction of a keyframe based interpolated format (eg. mpeg) but these could
provide some interesting compost.. .. ) ))

using data from running video textures as a source of pdata, could also
provide some interesting diversions. ..
