Eric Anholt e6d6a10c5a i965/gen7: Fix depth buffer rendering to tile offsets.
Previously, we were saying that everything from the starting tile to
region width+height was part of the limits of our depthbuffer, even if
the tile was near the bottom of the depthbuffer.  This mean that our
range was not clipping to buffer buonds if the start tile was anything
but the start of the buffer.

In bebc91f0f3, this was changed to
saying that we're just rendering to a region of the size of the
renderbuffer.  This is great -- we get a range that should actually
match what we want.  However, the hardware's range checking occurs
after the X/Y offset addition, so we were clipping out rendering to
small depth mip levels when an X/Y offset was present.  Just add
tile_x/y to the width in that case -- the WM won't produce negative
x/y values pre-offset, so we just need to get the left/bottom sides of
the region to cover our buffer.

Fixes the following Piglit regressions on gen7:
    spec/ARB_depth_buffer_float/fbo-clear-formats
    spec/ARB_depth_texture/fbo-clear-formats
    spec/EXT_packed_depth_stencil/fbo-clear-formats

NOTE: This is a candidate for the 8.0 branch.

Quick Start
----- -----

Windows drivers are build with SCons.  Makefiles or Visual Studio projects are
no longer shipped or supported.

Run

  scons osmesa mesagdi

to build classic mesa Windows GDI drivers; or

  scons libgl-gdi

to build gallium based GDI driver.

This will work both with MSVS or Mingw.


Windows Drivers
------- -------

At this time, only the gallium GDI driver is known to work.

Source code also exists in the tree for other drivers in
src/mesa/drivers/windows, but the status of this code is unknown.


General
-------

After building, you can copy the above DLL files to a place in your
PATH such as $SystemRoot/SYSTEM32.  If you don't like putting things
in a system directory, place them in the same directory as the
executable(s).  Be careful about accidentially overwriting files of
the same name in the SYSTEM32 directory.

The DLL files are built so that the external entry points use the
stdcall calling convention.

Static LIB files are not built.  The LIB files that are built with are
the linker import files associated with the DLL files.

The si-glu sources are used to build the GLU libs.  This was done
mainly to get the better tessellator code.

If you have a Windows-related build problem or question, please post
to the mesa-dev or mesa-users list.
