This protocol is wayland-like though it uses a slightly different message format. The XML file uses the same structure, except for the "fixed" type which is "float" here. The scanner uses a jinja template to generate source and header files for ei and eis which are now used instead of the protobuf-generated objects. Note that the scanner is a minimal working version, some features like enum value checks are not yet implemented. Unlike wayland we do not need to generate the libwayland-like library, we only need the wire protocol parser - some shortcuts can thus be taken. To keep the changes simple, the protocol currently is a flat protocol with only one interface and all messages copied over from the previous ei.proto file. In future commits, this will be moved to the respective interfaces instead.
