Just like in other web clients, size is the size in characters the field should be,
max_size is the maximum length in characters that can be entered.
default_text is the text the user wants to have appear in the textfield
on creation and reset.
The layout needs the front end to fill in the width and height fields in the
LO_FormElementStruct. It also needs the baseline field filled in.
This may be difficult to impossible on some front ends. baseline is
the y position from 0 to (height - 1) that should line up with regular text on
the same line as this form element. If necessary, just punt to
baseline = (height - 1).

/* Why we invalidate a slightly larger rectangle than that occupied by the form element
pane itself: when generating a page from HTML, the compositor creates a unique layer
for each form element. This layer is strictly rectangular and slightly larger than
the form element pane, and is used as a mask to punch out a hole in its background.
If the new form element happens to be located in a table cell using a background
color different from that used by the document, the element will have a frame
of the document background color around it after the document has been created.
That frame is temporary; it is erased when the document is redrawn, because on
subsequent draw operations, the element frame is no longer used to punch a hole
in the cell background. The cell background is rendered in the same pass as the
document background, before PowerPlant panes (already created form elements) are
drawn. Invalidating a slightly larger framerect when the form element pane
is first moved onto the document forces the important part of that redraw to happen
immediately, erasing the inappropriately colored frame around the pane.
