Contains some smaller fixes and renaming of macros. Looks big,
but isn't scary at all ;)

This change moves the w, h, d variables to QPixmapData and introduces
is_null to keep track of nullness. This is possible only because
QPixmapData is internal API; otherwise we'd have to be smarter.
The optimization makes the QPixmap::width() function take 7 instructions,
down from 34 before. For the calculator demo in the declarative ui branch
this reduces a block of 750000 instructions (out of 30000000) to around
100000-150000 instructions.
Tested on Windows, Linux, Mac. Raster, X11 and OpenGL paint engines. Have
not tested the DirectFB engine.

Avoid needless DPI calculations when not needed, and simplify the DPI
calculations to the point where most of the operations disappear. Also
avoid calling QImage::metric() so that we don't need to go through two
switch statements and an extra function call just to get the width of a
pixmap.
