Subject: [ANN] ruby-opengl 0.60.0 released

Hello,

we've just released version 0.60.0 of the OpenGL bindings for ruby.

Changes:
* Automatic error checking for GL/GLU calls, enabled by default (see 
doc/tutorial)
* Added support for many more OpenGL extensions
* Support for Ruby 1.9.0+ (requires mkrf 0.2.3)
* Ton of bugfixes.

API Changes:
* Boolean functions/parameters was changed to ruby true/false instead of 
GL_TRUE / GL_FALSE, which remains for compatibility
* glGet* functions now returns x instead of [x] when returning only one value
* Functions operating on packed strings (glTexture, gl*Pointer etc.) accepts 
ruby arrays directly
* Matrix handling functions also accepts instances of Matrix class, or any 
class that can be converted to array
* glUniform*v and glUniformmatrix*v now does not require 'count' parameter, 
they will calculate it from length of passed array
* glCallLists needs type specifier (previously was forced to GL_BYTE)
* On ruby 1.9, glut keyboard callback returns char ("x") instead of integer so 
using 'if key == ?x' works on both 1.8 and 1.9

There has been lots of code changes since last release, so expect some bugs. 
This release marks pretty much completion of the low-level API (before OpenGL 
3.0 hits us), meaning there shouldn't be much things you can do in C OpenGL 
that you couldn't do in ruby. There is still no API documentation (planned 
for next release), although most of the functions follows their C 
counterparts with the same patterns and changes outlined in tutorial section 
of our homepage. Also, performance freaks will be happy to hear that with 
ruby 1.9.0, the raw speed of OpenGL operations now matches the speed of 
Perl's POGL bindings (at least according to my tests), which is between 2x-5x 
increase from ruby 1.8.

As always, any feedback is appreciated.
