Override create/destroy picture to track pict format.

Browse Source 
When create a piccture, we need to attach a pixmap to it.
A pixmap only has a depth, which is not sufficant for glamor.
As in openGL texture only has a few internal formats which
is not sufficant to represent all the possible picture
format. So we always transform the picture format to GL_RGBA.
And when we need to read back the picture, we must know the
original picture format. So we have to override create
and destroy picture to track a pixmap's real picture format
if it is attached to a picture.
