[PD] gem: resize a texture / buffering textures

[Thoralf Schulze]

hi there,

with regard to this thread:
http://lists.puredata.info/pipermail/pd-list/2006-09/041759.html
- is there a way to resize a texture in gem?
i'm aware of pix_resize, but this object is slow as
hell and only resizes to the next power of two. i'm
looking for something that does a fast resize to an
arbitrary size - my plan is to cut the time it takes
the pix_buffer-objects to store and recall textures.

on a related note: is it possible to buffer textures
created by pix_buffer_read so that the texture will
only be updated if the content of the buffer has
actually changed? i figured that it might be enough to
only snap every 4th frame and use a buffered version
of the textures for the other render cycles ... 
but pix_buffer_read does the texture upload every
render cycle, and i couldn't get pix_buf to actually
buffer a texture ...
i'm probably making not much sense here, please have a
look at the attached patch to see what i'm up to.

thank you very much for your input,
thoralf.
