GetTextExtent
Purpose
This wraps the call to GetThemeTextExtent, which returns
the area that will be taken up by drawing themed text.
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 )
pszText - the text to measure
iCharCount - the number of characters to draw
dwTextFlags - the text style to use when measuring the text area
pBoundingRect - the rect to draw text into
pExtentRect - used to return the rect which will be used by the text.
Return
A HRESULT to indicate success or failure.

// Windows Vista *without* SP1
// ---------------------------
// The Vista 'TOOLTIP' theme offers a bold version of the standard tooltip font via
// the TTP_STANDARDTITLE part id. Furthermore TTP_STANDARDTITLE is the same font as
// the standard tooltip font (TTP_STANDARD). So, the 'TOOLTIP' theme can get used
// thoroughly.
//
// Windows Vista *with* SP1
// ------------------------
// The Vista SP1(!) 'TOOLTIP' theme does though *not* offer a bold font. Keep
// in mind that TTP_STANDARDTITLE does not return a bold font. Keep also in mind
// that TTP_STANDARDTITLE is even a *different* font than TTP_STANDARD!
// Which means, that TTP_STANDARDTITLE should *not* be used within the same line
// as TTP_STANDARD. It just looks weird. TTP_STANDARDTITLE could be used for a
// single line (the title line), but it would though not give us a bold font.
// So, actually we can use the Vista 'TOOLTIP' theme only for getting the proper
// tooltip background.
//
// Windows XP
// ----------
// Can *not* use the 'TOOLTIP' theme at all because it would give us only a (non-bold)
// black font on a white tooltip window background. Seems that the 'TOOLTIP' theme under
// WinXP is just using the default Window values (black+white) and does not
// use any of the tooltip specific Window metrics...
