The way that the GtkTreeView calculates sizing is pretty confusing.
This is written down to help keep track of it in my head, and thus help
anyone who hopes to work with the code in the future.

HOW THE GTKTREEVIEW CALCULATES SIZE:
====================================
When the view is given a new model, the first thing it does is walk
When the view is given a new model, the first thing it does is walk
through the model at the top level, creating an GtkRBNode for each
element of the model. Each node has a height of 0. The RBTree is kept
updated as the models structure changes. Additionally, the user can
expand, collapse, and select rows at this stage. The RBTree is accurate
-- it just doesn't have a height for any row.
When the TreeView is realized, it calculates the actual height of each
row by walking the tree and measuring them. While doing so, it gets the
size of each column.
Columns are initially marked as 'dirty'. When sized,
gtk_tree_view_check_dirty_and_clean () is called on each column. This
function walks through all visible columns, and sees if they're dirty or
not. If any are dirty, it then walks the tree, calling
gtk_tree_view_calc_size on each row. gtk_tree_view_calc_size requests
the size of every dirty column in the tree. Finally, it updates the
size of the widget (including adjustments).
-- it just has a height of zero for every row.
When the widget is realized, it calls install_presize_handler, to setup
the first-run function. This is run before the expose event.
HOW THE GTKTREEVIEWCOLUMN STORES SIZE:
======================================
@ -32,23 +21,46 @@ HOW THE GTKTREEVIEWCOLUMN STORES SIZE:
There are a number of size related fields in the GtkTreeViewColumn
structure. These are all valid after realization:
sizing The sizing method to use when calculating the size
of the column. Can be grow_only, resizable, auto, and fixed.
column_type The sizing method to use when calculating the size
of the column. Can be GROW_ONLY, AUTO, and FIXED.
requested_width The width of the column as requested by the column
button_request The width as requested by the button.
width The actual width. This is requested width for all
columns but possibly the last one.
requested_width The width of the column as requested by the column.
It is the max requested width of the bcells in the
column. If the column_type is AUTO, then it is
recalculated when a column changes. Otherwise, it
only grows.
resized_width The width after the user has resized the column.
width The actual width of the column as displayed.
fixed_width The requested fixed width for the column iff it's
sizing type is set to GTK_TREE_VIEW_COLUMN_FIXED.
Used instead of requested_width in that case.
min_width The minimum width the column can be
min_width The minimum width the column can be. If set to -1,
this field is considered unset.
max_width The maximum width the column can be. This can be
overridden for the last column, if the tree_view is
actually wider than the sum of all of the columns
requested_widths.
requested_widths. If set to -1, this field is
considered unset.
use_resized_width Use resized_width to determine the size.
--
tree_view->priv->width = the width the widget wants to be, including headers.
tree_view->priv->height = the height the widget requests. It's the sum
of the width of all visible columns.
Both of these are calculated in _gtk_tree_view_update_size
