SDK upgrade is necessary to support dynamic/webfont because SDK 6.0 does not have
t2embapi.h and t2embed.lib. SDK 6.1 is compatible with WIn XP and VS 2005 or later.

FYI:
http://codereview.chromium.org/14084/show is the CL for adding web/dynamic font support.

and better-thought-out Hammer env.Bits() idioms:
* env['PLATFORM'] == 'win32' => env.Bit('windows')
* env['PLATFORM'] == 'posix' => env.Bit('linux')
* env['PLATFORM'] == 'darwin' => env.Bit('mac')
New idioms:
* env.Bit('posix') => really does mean "any POSIX platform"
* env.AnyBits('mac', 'linux') => specifically mac or linux, excluding
  other POSIX platforms
Where we were using compound conditionals (e.g., "env['PLATFORM'] in
('posix', 'darwin')") I tried to take my best shot at translating
the intent (i.e., "env.Bits('posix')" for something POSIX, "not
env.Bits('mac')" for something not yet ported to Mac, etc.)

* Configurable CHROME_BUILD_TYPE command line or external environment
  variable for selecting appropriate release_impl*.scons settings
  (_checksenabled, _coverage, _dom_stats, _official, _purify).
* Configurable CHROMIUM_BUILD command line or external environment
  variable for selecting appropriate chromium_build*.scons settings
  (_google_chrome).
* Configurable /INCREMENTAL linking via command line or external
  environment variable ($INCREMENTAL), through appropriate setting
  of an internal $CHROMIUM_INCREMENTAL_FLAGS construction variable.
* Full link of release builds by default.
* Alphabetize *.scons files in the mac_env.FilterOut() list.
* Explicitly set _checksenabled.scons link flags.

It was brought to my attention that defining _HAS_TR1=0 helps with Visual Studio 2008 compilation and causes no adverse effect on Visual Studio 2005.

Thanks to Daniel A. White for the tip.

* Add third_party/purify/pure_api.c to the base\base_lib.scons sources.
* Support specification of CHROME_BUILD_TYPE (and CHROMIUM_BUILD
  while we're here) either on the command line or as an
  external environment variable.
* Fix syntax error in release_impl_purify.scons (previously unused).
* Add a central $CHROMIUM_CC_OPT_FLAGS variable (included in $CCFLAGS)
  that can be used to set explicitly the optimization level without
  having to worry about optimization flags being pulled in from other
  settings files.

build\*.scons structure (mirroring build\*.vsprops files):
* Use env.ApplySConscript() instead of env.SConscript with a
  hand-crafted dictionary defining 'env'.
* Move various CPPPATH, CCFLAGS, CPPDEFINES, LIBS and LIBPATH
  definitions from build/SConscript.main and target-specific 
  *.scons files into the build\*.scons files that mirror the
  existing build\*.vsprops hierarchy.
* Use the new build\{debug,release}.scons files to update the
  windows_dbg and windows_opt construction environments.
* Mirror current support for CHROME_BUILD_TYPE and CHROMIUM_BUILD
  external environment variables.
* Remove hard-coded /TP options.
* Massage $CXXFLAGS to remove $CCFLAGS, avoiding duplication of options
  on command lines.  Handle the ripple effect in $PCHCOM by adding
  $CCFLAGS back to that command line.
* Delete hammer's default settings of {CC,LINK}FLAGS_{DEBUG,OPTIMIZED}
  so they don't pollute our construction environments.
* Update chrome config to link against v8 for opt, v8_g for dbg.
* Get rid of fragile by-hand order of using_net.scons before other
  using_*.scons files.  We're now using --start-group and --end-group
  on Linux to deal with dependency cycles in libraries.
