+experimental stuff
+
+todo:
+
+* modify 2D rotation to be used as arbitrary rotation (givens)
+* add 3D rotation
+* frame rate limited delay line (burst delay?)
+* optimize resampling code (mipmapped packed 16bit format?)
+
+
+* cache slicer
+
+pdp_slice_cut & pdp_slice_glue seem to have a significant impact on performance
+for long chains with simple (memory rate limited) operators. especially when a lot
+of passive packets are involved. todo: make a vertical slicer + mmx transpose object
+to use this for horizontal and vertical processors too (vertical processors: more efficient
+because of alignment). find out why this doesn't work in threads + think about a possibility
+to do first layout a buffer structure, and then do incremental processing (outside of pd/pdp:
+for constructing optimized signal processors using some kind of intermediate language
+and automatic slice dimension selection)
+NOTE: solve this as a forth script for specific abstractions.
+
+* new image packet types
+
+*) PDP_IMAGE_MCHP
+
+multi channel stuff. this packet type is to solve some problems with the subsampled
+chroma planes in PDP_IMAGE_YV12. although it is fast, it is best to have an equally 
+sampled, arbitrary number of channels image type available. 
+
+
+*) PDP_IMAGE_PCK4
+
+the main reason for this package type is in resampling code to have single pixel 
+access mmx routines. but is it worth it? probably not.. mipmap image packet for resampling?
+
+
+* new vectors, matrices & gsl packets
+
+general matrix math is a nice thing to have. wrapping gsl is a possibility. it can use
+atlas for fast matrix math. finish better type handling first.
+
+
+* opengl -> see also opengl/TODO
+
+move opengl stuff to dpd.
+todo:
+- think about pbufs / textures : isolate system specific stuff
+
+
+* better type handling
+
+core is in place. todo:
+- better (tree) search algorithm (breadth first + cost)
+- add more converters
