Two tweaks for accelerated painting:

Two tweaks for accelerated painting:
. Make sure if there is no texture and we're told to paint, we paint
  to the whole texture (see comment for details on why we need to do
  this).
. When the transform changes only schedule paint on the widget. By doing
  this we won't trigger updating the texture, only having the
  compositor redraw everything. This currently doesn't matter, but
  will once James lands his changes to SchedulePaint to keep a dirty
  bit.

LGTM

File views/view.cc (right):

http://codereview.chromium.org/7056013/diff/2002/views/view.cc#newcode416
views/view.cc:416: if (!texture_.get()) {
don't you need this to be #if defined(COMPOSITOR_2)?

http://codereview.chromium.org/7056013/diff/2002/views/view.cc#newcode1184
views/view.cc:1184: if (!texture_.get()) {
again with the ifdefs

GAH! I added the first ifdef. The second one isn't needed because PaintToTexture
is already wrapped in #ifdef COMPOSITOR_2.

LGTM, too.
