From: Dongwon Kim <[email protected]>

The EGL surface and context are destroyed when a new GTK window is
created. We must ensure these are recreated and initialized before
any rendering happens in gd_egl_refresh.

Currently, the check for a pending draw is performed before the
surface initialization block. This can result in an attempt to
draw when the EGL surface (vc->gfx.esurface) is not yet available.

This patch moves the drawing check after the surface initialization
to ensure a valid surface exists before rendering in gd_egl_refresh.
