ecore-evas-x: set draw_block until the window receives a configure event (#2) 

Summary:
drawing a non-override window before receiving a configure event results
in an unsized window, breaking spec. it also prevents ecore-evas resize
callbacks from triggering, yielding undefined returns from functions which
attempt to get the geometry of the ecore-evas

this patch improves upon the previous version by handling the case of windows
which are created with the correct initial size, bypassing an initial configure
event

there is still a lot of work to be done in this engine to improve/consolidate
resize-related code and ensure protocol correctness
