* ARGB8 and BGRA8 formats now support sRGB -> linear conversion if sRGB pipeline is used, previously they were ignored.
* All float and half float formats are considered supported if we either support OpenGL 3 or ARB float texture.
* Cleanup TextureUtil a bit by removing constant references from ARBHalfFloatPixel, ARBTextureFloat, EXTPackedFloat, EXTTextureSharedExponent and EXTTextureSRGB to GL21 and GL30 classes (which are identical anyway).
* Check if we support sRGB textures before choosing sRGB format (although this check should have been done earlier? not sure..)
- Add instanced geometry support. This is performed by uploading 4 vertex buffers each containing 4 floats. The top 3 rows are the world matrix and the bottom row is a quaternion representing the normal matrix. Hence, both unshaded and lit geometries can be rendered through instancing.
See Instancing.glsllib for more information as well as the comment in LwjglRenderer.
One can now mark a texture param in a material definition as linear by using -Linear at the end of the parameter declaration (case insensitive).
An Image bound to a material texture param in a linear color space will have its ColorSpace set to linear when bound to the material by mat.setTexture("name", texture);
Added the -LINEAR flag to all texture param that needed it in stock materials (lighting.j3md, terrainLighting.j3md, different Filter materials).
- All images constructors now take the isSrgb flag as a parameter, all engine classes has been changed to accommodate the change, old constructors has been deprecated for backward compatibility. One should always ask himself in which color space is an image if dealing with gamma correction
- Gamma correction has been defaulted to false in the appSettings
