OpenGL rendering is now done into sRGB framebuffer. OpenGl_ShaderManager::prepareStdProgramFboBlit() has been extended by programs resolving MSAA texture and applying gamma correction as fallbacks. Quantity_Color definition has been modified to store RGB components in linear color space within Quantity_TOC_RGB type. Standard colors defined by Quantity_NameOfColor enumeration has been updated accordingly. New Quantity_TOC_sRGB type has been introduced to handle RGB components in non-linear sRGB color space. OpenGl_TextureFormat class definition has been moved to dedicated files. New method OpenGl_TextureFormat::FindFormat() replaces OpenGl_Texture::GetDataFormat(). New method OpenGl_TextureFormat::FindSizedFormat() replaces OpenGl_FrameBuffer::getColorDataFormat() and OpenGl_FrameBuffer::getDepthDataFormat(). Graphic3d_TextureRoot::IsColorMap() - introduced new property defining if RGB(A)8 image formats should be loaded as sRGB(A) textures or as data RGB(A) textures. OpenGl_Texture initialization methods have been extended with new theIsColorMap argument. vreadpixel - added argument -sRGB printing color in sRGB color space. Test cases have been updated to new sRGB rendered results.
