Steps to reproduce the problem:
If we create a PictureImageLayer in CV side, and try to display an image in it. Its not showing properly.
Also layer masking also not working if we do it in CV side.

What is the expected behavior?
Both Image display and masking should work properly.

What went wrong?
Issue happens due to ResourceProvider::GetImageTextureTarget returigit ng wrong GLenum. 
Since the buffer_to_texture_target_map_ is empty for browser process.
But for renderProcess it has proper values.

GLenum ResourceProvider::GetImageTextureTarget(gfx::BufferUsage usage,
                                               ResourceFormat format) {
  gfx::BufferFormat buffer_format = BufferFormat(format);
  auto found = buffer_to_texture_target_map_.find(
      BufferToTextureTargetKey(usage, buffer_format));
  DCHECK(found != buffer_to_texture_target_map_.end());
  return found->second;
}

Did this work before? N/A
