DrvTextOut()
General Plan:
--------------------
*
* On every TextOut, GDI provides an array of 'GLYPHPOS' structures
* for every glyph to be drawn. Each GLYPHPOS structure contains a
* the glyph. (Note that unlike Windows 3.1, which provides a column-
* major glyph bitmap, Windows NT always provides a row-major glyph
* bitmap.) As such, there are three basic methods for drawing text
* with hardware acceleration:
*
* 1) Glyph caching -- Glyph bitmaps are cached by the accelerator
* (probably in off-screen memory), and text is drawn by
* referring the hardware to the cached glyph locations.
*
* 2) Glyph expansion -- Each individual glyph is colour-expanded
* directly to the screen from the monochrome glyph bitmap
* supplied by GDI.
*
* 3) Buffer expansion -- The CPU is used to draw all the glyphs into
* a 1bpp monochrome bitmap, and the hardware is then used
* to colour-expand the result.
*
* The fastest method depends on a number of variables, such as the
* colour expansion speed, bus speed, CPU speed, average glyph size,
* and average string length.
