render_as_template template tag

This is a template tag that works like `{% include %}`, but instead of loading a template from a file, it uses some text from the current context, and renders that as though it were itself a template. This means, amongst other things, that you can use template tags and filters in database fields. For example, instead of: `{{ flatpage.content }}` you could use: `{% render_as_template flatpage.content %}` Then you can use template tags (such as `{% url showprofile user.id %}`) in flat pages, stored in the database. The template is rendered with the current context. Warning - only allow trusted users to edit content that gets rendered with this tag.

ImageMagick commands from Django Templates

A template filter which wraps imagemagick's `convert` command. The filter acts upon a source image path, and returns the filtered image path. usage: {{ source_path|convert:"-resize 64x64\!" }} The filter parameter is the processing arguments for an ImageMagick 'convert' command. See e.g. http://www.imagemagick.org/Usage/resize/ Every image created is saved in a cache folder. This code does not handle removing obsolete cached images. If the filtered image path exists already, no image processing is carried out, and the path is returned.
