Attaching a picture to a pixmap doesn't change its GL format, so it
doesn't change how core rendering should be assigning colors to it.
(Imagine XCreatePixmap(), optional XCreatePicture(pixmap) with various
formats, XFillRectangle, XGetImage(). If the XGetImage results
changed, this would be wrong).

This avoids a lot of screwing around to attach our privates later. It
means that non-glamor pixmaps now gain 120 bytes of glamor privates on
64-bit (which has quite a bit of fixable bloat), and glamor pixmaps
take one less pointer of storage (not counting malloc overhead).
Note that privates start out zero-filled, which matches the callocs we
were doing when making our own privates, and in the case of an fb
pixmap that has a priv where it didn't before, the type ends up being
GLAMOR_MEMORY as we would want.
v2: Clarify that the GLAMOR_MEMORY enum must be 0 (as it was
previosuly), so that the new pixmap private behavior is as
expected. Suggested by keithp.

Fixes regressions since Eric's "don't make an FBO for the glyph atlas"
change. The a1 upload was a fallback, as expected. However, fallback
reads use glReadPixels() because there's no glGetTexSubImage2D() to
match glTexSubImage2D(). We were just binding the 0 FBO value, so the
glReadPixels() would throw a GL error instead of getting any data.
After the fallback was done we'd write back the undefined data to the
atlas, blowing away the entire rest of the atlas because we didn't
specify any bounds on our prepare.
To fix the fallbacks to actually work, we'd need a prepare path that
allocates some memory memory do a full glGetTexImage() into, then
memcpy out of that. Instead, just dodge the general fallback by
implementing the specific upload we need to do here, which should also
be *much* faster at uploading a1 glyphs since it's not
readpixels/texsubimaging back and forth.
