------------------------ RELEASE 1.8.0 ------------------------
This is a major release, with several big new features. As such,
it is likely to contain bugs.
* True threading support now enabled in the default build
* Pipelined rendering: app, cull, and draw can run in parallel, each
in their own thread
* Web plugin is more robust, and better supports Safari and Chrome
* Plugin runs properly when the username contains non-ASCII characters on Windows
* Added appRunner.p3dFilename and appRunner.p3dUrl to provide p3d
location
* Multifiles (and p3d files) now make a distinction between binary and
text files

* Ambient occlusion generation for terrain
* Fixed bug where Windows installer wipes %PATH% when it's too long
* Added fog support to the shader generator
* Added normal_gloss texture mode
* Added a custom color option to the cartoon filter
* Support for texture arrays in shaders
* Better shader support in pandadx9
* Fix some issues with cube map buffers
* Can be compiled to use double-precision floats throughout, instead
of the default of single-precision floats. (Graphics drivers still
use single-precision floats, of course.)
* Can be compiled with the optional Eigen library to provide SSE2 support
* Can be compiled with SpeedTree support
* Can be compiled on MSVS2010, and/or Win64. (These builds not
provided by default.)
* Support for the Bullet physics engine
* Support for the libRocket GUI library
* Support for stereo/multiview textures
* Substantial performance improvements to movie textures
* TGA files with alpha channel now load correctly
* New "Ramdisk" mount type available for the VFS
* The VFS is now writable for ramdisk files and true on-disk files
* pdeploy -i generates a custom icon for the installed game
* wx and tk work better on OSX

platforms (including OSX) with the new WxPandaWindow class
* Added base.pixel2d for pixel-based 2-D coordinates
* Python-based swizzling of Panda vectors, e.g. vec2.xyxy
* Python programmers can now optionally use the original unmangled C++
name for methods and classes, e.g. model.set_pos(LPoint3f(1, 2, 3)).
* Command-line filename globbing now supported on Win32, e.g. egg-texture-cards *.png
* DirectGui works with nonstandard coordinate-system in effect
* Egg loader handles double-sided polygons a little differently by
default now, for better render performance but more memory usage
(use "egg-emulate-bface 0" to restore the old behavior if needed).
