/********************************************
GetMargins
Purpose
This wraps the GetThemeMargins call, which returns the margins of the area
which will be taken up by drawing the theme edge.
Params
hwnd - the window to draw to, often NULL
hdc - the HDC to draw to
type - the cell type to draw
state - the state of the cell ( selected, current, etc )
propId - the margin type to return
prc - the rect to draw to
XPMARGINS - an internal struct which copies the MARGINS struct, so this code
will work if the XPThemes header files are available or not.
Return
A bool to indicate success or failure.
