GITechDemo:

* tuned some parameters, particularly for tonemapping
* fixed a couple of memory leaks

GITechDemo:

*remove ImGui test window

GITechDemo:

*lighting parameter update
*tone mapping parameter update
*bloom parameter update
*film grain parameter update
*color correction parameter update
*default to borderless window mode
*window state caching initialization fix

GITechDemo:

*The HDR tone mapping pass now also performs color correction through the use of a 3D color lookup table
*Added anamorphic bokeh effect as an option (disabled by default)
*Lens flare textures now have full mip chain

Synesthesia3D:
*Fixed an issue where the addressing mode on the W axis for 3D textures was not properly set

Added information about the new PBR textures

Synesthesia3D:

*added support for infinite projection matrix
*fixed potential usage of uninitialized variable in ShaderProgramDX9.cpp

GITechDemo:
*added an artist parameter to control whether or not to use infinite projection matrix (used by default)
*fixed sky box issues caused by infinite projection matrix
*fixed an issue in DirectionalLight.hlsl in which some combination of camera, light and normal angles would cause a division by zero
*fixed build scripts exit codes
*commented code which set thread priorities in framework (it seemed to have caused occasional frame spikes)
*FXAA is now applied based on a depth based edge detection system so as to minimize texture blurring
*implemented support for borderless windowed mode
*volumetric fog color is now an artist control
*adjusted default parameters

GITechDemo:

*fixed bug with BRDF model switching

GITechDemo:

*added sanity checks for textures that are required to generate GBuffer
*moved sky pass after SSR in order to avoid reflecting the sun and sky
*removed lens distortion effect due to blurring
*updated Sponza model with some geometry to make volumetric lighting more prominent

*updated readme

*fixed tabs
*fixed typo
