included SSAO files for rendering example
blur shader not working, investigating
corrected blur shader and fbo depth buffer
rewriting SSAO shaders, missing noise texture and other parameters
SSAO working without sampling, brute force kernel
new shader names for ssao
corrected default values for SSAO
added ssao intensity value slider
added ssao max dist value slider
ssao working without noise function, added toon shader
improving rendering example, included toggle draw trackball, improved ssao sampling, but not yet great
separated SSAO methods and prepared for offscreen rendering for snapshots for example
corrected final SSAO pass, blurs only SSAO result and not entire image
added link error log to shader class
corrected pro files
