/// The compiler setting also determines the function version. If Unicode is defined, the function call resolves to PreloadTextW. Otherwise, the function call resolves to PreloadTextA because ANSI strings are being used. This method generates textures that contain glyphs that represent the input text. The glyphs are drawn as a series of triangles. Text will not be rendered to the device; ID3DX10Font::DrawText must still be called to render the text. However, by preloading text into video memory, ID3DX10Font::DrawText will use substantially fewer CPU resources. This method internally converts characters to glyphs using the GDI function {{GetCharacterPlacement}}.

If there are multiple lines of text, ID3DX10Font::DrawText uses the width of the rectangle pointed to by the pRect parameter and extends the base of the rectangle to bound the last line of text. If there is only one line of text, ID3DX10Font::DrawText modifies the right side of the rectangle so that it bounds the last character in the line. In either case, ID3DX10Font::DrawText returns the height of the formatted text but does not draw the text. DT_CENTER Center text horizontally in the rectangle. DT_EXPANDTABS Expand tab characters. The default number of characters per tab is eight. DT_LEFT Align text to the left. DT_NOCLIP Draw without clipping. ID3DX10Font::DrawText is somewhat faster when DT_NOCLIP is used. DT_RIGHT Align text to the right. DT_RTLREADING Display text in right-to-left reading order for bidirectional text when a Hebrew or Arabic font is selected. The default reading order for all text is left-to-right. DT_SINGLELINE Display text on a single line only. Carriage returns and line feeds do not break the line. DT_TOP Top-justify text. DT_VCENTER Center text vertically (single line only). DT_WORDBREAK Break words. Lines are automatically broken between words if a word would extend past the edge of the rectangle specified by the pRect parameter. A carriage return/line feed sequence also breaks the line. ? </param>
