DirectDraw 1 applications tend to not be especially performance
critical on modern hardware, so in that regard it's fine. What is a
concern though is d3d_execute_buffer_execute_pick() diverging from
d3d_execute_buffer_execute() when changes are made to one or the
other.

Having tests is important, both in order to be sure the implementation
is correct as well as to prevent future changes from breaking it.
