Bump protocol version to 1.4.
Bump package version to 2.7.
This new protocol request effectively allows clients to perform feature
detection on the DDX.
If I had DRI2GetParam in June 2011, when I was implementing support in the
Intel DDX and Mesa for new hardware that required a new DRI2 attachment
format, then I could have avoided a week of pain caused by the necessity
to write a horrid feature detection hack [1] in Mesa. In the future, when
the work begins to add MSAA support to the Intel DDX, having a clean way
to do feature detection will allow us to avoid revisiting and expanding
that hack.

Just add a new struct to remain compatible with existing code.

This reverts commit 0ca3778de195a82087d0f07415a1cf8fc94f5b0a.
This broke compatibility by renaming existing struct fields. So revert
in favor of a new struct.

We only spec a 32 bit sbc count, so drop the high bits. Also make the
padding explicit.

Needed to handle swap interval in the direct rendered case.

Length should be a CARD32 and match the endianness annotation.

Based on SGI_video_sync, SGI_swap_control and OML_sync_control, add swap
interval and synchronization support to DRI2. Useful for throttling rendering
and basic performance metrics.

The protocol now require a DRI2GetBuffersWithFormat request to follow the
swapbuffer request so.
|

|

Add a SwapBuffers request for requesting a front<->back swap. Returns a
whole new set of buffers to the client to allow for triple buffering
etc.

This function replaces DRI2GetBuffers.

Still to resolve is the swap buffer request. It should probably be
broken into two requests, one to post the swap request and one to wait
for it to be completed. Also, need to find a good solution to
CopySubBuffer that doesn't require a roundtrip per rectangle.
Don't need to solve all this for 2.0, though, can add requests later on.

Also, remove the screen number where it's redundant and rename
drmDrawable in the create drawable request to just 'handle' now that
we don't rely on drm drawables.
