// This class is now mostly finished, except one thing, it is a global
// object. This will not do. The user (and layout files) are free to
// create floats and modify them to fit into a certain document. So it is
// pretty clear that each layout needs its own list, as do documents.
// However this is also not enough since we really want the user to be
// able to create "presistent" floats, in the sense that a user created
// float can be used across sessions and across documents. So we need a
// global¹ floatlist as well. The interaction between these are not quite
// clear, but it seems natural that the definition found in the document
// takes precedence.
// We also have the issue about what get stored _in_ the lyx file.
//
// ¹ not absolutely global but somewhere where documents,layouts and
// the bufferview can have access to it.
