Subject: (w32_read_socket): Remove unused WM_ERASEBKGND code.
X-Git-Tag: emacs-19.34~211
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=ded385e2a01439537afb9ff1d0ebb84cbe3a1fbb;p=emacs.git

(w32_read_socket): Remove unused WM_ERASEBKGND code.
No need to erase background now on (delayed) WM_PAINT.  Move
WM_PALETTECHANGED processing to raw input thread.
