The main changes are twofold: * Buffer flipping is now controlled by the m_screen_can_set_buffer flag in WSCompositor. This flag, in turn, is impacted by m_can_set_buffer flag, in WSScreen. m_can_set_buffer is set in the WSScreen constructor by checking the return value of fb_set_buffer. If the framebuffer supports this operation, it will succeed, and we record this fact. This information is then used by WSCompositor to set its own m_screen_can_set_buffer flag. * WSScreen now only requests a resolution change of the framebuffer. The driver itself is ultimately responsible for what resolution or mode is actually set, so WSScreen has to read the response from that request, and has no choice but to accept the answer. This allows the driver to choose a "close enough" value to what was requested, or simply ignore it. The result of this is that there is no special configuration necessary for WindowServer to work with reduced-capability framebuffer devices.
