Alpha palettes have two uses: 1) for masks, 2) to split colour inputs into single colour channels, or to combine single colour channels into a combined channel. The order of colour channels is the same as the order in the combined channel. For example if an input in RGB24 palette is split into 3 non-mask alpha channels, then the alpha channels will be in the order: Red, Green, Blue. A single non-mask alpha channel would represent the luminance.

A port is a set of one or more properties
Each port has a mandatory property called "type" (see below), depending upon "type" property port has other mandatory and optional properties.
"type" can be one of:
* LIVIDO_PORT_TYPE_PLUGIN_INFO : Information about plugin and list of filter classes it includes
* LIVIDO_PORT_TYPE_FILTER_CLASS : Descriptive information about single filter class
* LIVIDO_PORT_TYPE_CHANNEL_TEMPLATE : Information about what kinds of channels filter accepts
* LIVIDO_PORT_TYPE_PARAMETER_TEMPLATE : Information about what kinds of parameters filter has
* LIVIDO_PORT_TYPE_FILTER_INSTANCE : All data about an instance
* LIVIDO_PORT_TYPE_CHANNEL : Instantination of a channel
* LIVIDO_PORT_TYPE_PARAMETER : Instantination of a parameter
* LIVIDO_PORT_TYPE_GUI : described in the separate livido GUI extension (TODO)
"type" is a single valued property with atom_type LIVIDO_ATOM_TYPE_INT.
The host should provide its own mediation layer for providing a datacontainer for its port.
This host uses the mediation layer, where a new port is defined.
