How about we call it clip_bounds_in_texture, region_of_texture,
draw_region_of_texture? Something to indicate that this is in texture space
(which is what we're clipping to).

Regardless, you need to update the compositor_gl.h and
chrome/browser/renderer_host/accelerated_surface_container_touch.cc to match
your new naming.

+   // clip clip_bounds_in_layer to size of texture
+   gfx::Rect clip_bounds = clip_bounds_in_layer.Intersect(
+       gfx::Rect(gfx::Point(0, 0), size_));

   if (params.blend)
     glEnable(GL_BLEND);
