   It would be useful for me too. Both AESv2 and MD filters profit from
   this, since they must cache all input too.

What about:
      
pdf_status_t pdf_stm_buffer_resize (pdf_stm_buffer_t BUFFER, pdf_size_t 
NEW_SIZE);

Resize a given buffer. 

If NEW_SIZE is larger than the actual size of @var{buffer} then BUFFER->size
will be increased, while both BUFFER->rp and BUFFER->wp will remain
unchanged. 

If NEW_SIZE is shorter than the actual size of BUFFER then the memory
pointed by BUFFER->data will be truncated, BUFFER->size will be
adjusted to the new value and both BUFFER->rp and BUFFER->wp will be
set to BUFFER->size if they are exceeding the new size of the buffer.

Would it fit your needs?
