wxWidgets/src/html/htmprint.cpp
Vadim Zeitlin c14dc5541c Fix PCH-less compilation after recent changes. 
Include wx/sizer.h explicitly when not using PCH.

// CSS specification offer following guidance on dealing with pixel sizes
// when printing at
// http://www.w3.org/TR/2004/CR-CSS21-20040225/syndata.html#length-units:
//
// Pixel units are relative to the resolution of the viewing device, i.e.,
// most often a computer display. If the pixel density of the output
// device is very different from that of a typical computer display, the
// user agent should rescale pixel values. It is recommended that the [
// reference pixel] be the visual angle of one pixel on a device with a
// pixel density of 96dpi and a distance from the reader of an arm's
// length. For a nominal arm's length of 28 inches, the visual angle is
// therefore about 0.0213 degrees.
//
// For reading at arm's length, 1px thus corresponds to about 0.26 mm
// (1/96 inch). When printed on a laser printer, meant for reading at a
// little less than arm's length (55 cm, 21 inches), 1px is about 0.20 mm.
// On a 300 dots-per-inch (dpi) printer, that may be rounded up to 3 dots
// (0.25 mm); on a 600 dpi printer, it can be rounded to 5 dots.
//
// See also http://trac.wxwidgets.org/ticket/10942.
