68c22efa58 From Thomas Hogarth, "Attached is a small build fix for PointSprite when compiling under GLES2 (r13788) 
GL_POINT_SPRITE_OES does not exist in GLES2, instead you just draw using GL_POINTS then use gl_PointSize in a vertex shader to set the size."

b199a334d9 Introduced OSG_GL*_FEATURES macros defined in include/GL that are set to 0 or 1 according to what the assocoated version of GL is compiled against. 
Removed EXT postfix of FrameBufferObject functions, and added support for checking non EXT versions frame buffer object GL functions.

Introduced usage of OSG_GL*_FEATURES to avoid some #if #else #endif code blocks.

Using a submissions from Paul Martz as a guide added perliminary GL3 support to a range of OSG classes

7cb1bcbd7d From Farshid Lashkari, "This patch adds a CoordOriginMode to the osg::PointSprite attribute. 
The mode needs to be changed to LOWER_LEFT when rendering point
sprites to pbuffers or FBOs, otherwise the points will be transformed
on the CPU."

871cc70c32 From Ravi Mathur, added extension checks for point sprite support. 
From Robert Osfield, tweaks of the above to use osg::buffer_object and a local struct to store
initialized to help with multi-thread and out of order context usage.
