half->float variants
// half->float variants.
// by Fabian "ryg" Giesen.
//
// I hereby place this code in the public domain.
//
// half_to_float_fast: table based
// tables could be done in a more compact fashion (in particular, can store tab2 in low word of tab1!)
// but something of a dead end since not very SIMD-friendly. pretty much abandoned at this point.
//
// half_to_float_fast2: use FP adder hardware to deal with denormals.

float->sRGB8 using SSE2 (and a table)
// float->sRGB8 conversions - two variants.
// by Fabian "ryg" Giesen
//
// I hereby place this code in the public domain.
//
// Both variants come with absolute error bounds and a reversibility and monotonicity
// guarantee (see test driver code below). They should pass D3D10 conformance testing
// (not that you can verify this, but still). They are verified against a clean reference
// implementation provided below, and the test driver checks all floats exhaustively.

QuantumCD / Qt 5 Dark Fusion Palette
Created August 15, 2013 21:40
This is a complete (I think) dark color palette for the Qt 5 Fusion theme, as well as a nice style sheet for the tool tips that make them blend better with the rest of the theme. To have immediate effect, be sure to put this in your main function before showing the parent window. Child windows should automatically inherit the palette unless you …
qApp->setStyle(QStyleFactory::create("Fusion"));
QPalette darkPalette;
darkPalette.setColor(QPalette::Window, QColor(53,53,53));
darkPalette.setColor(QPalette::WindowText, Qt::white);
darkPalette.setColor(QPalette::Base, QColor(25,25,25));
darkPalette.setColor(QPalette::AlternateBase, QColor(53,53,53));
darkPalette.setColor(QPalette::ToolTipBase, Qt::white);
darkPalette.setColor(QPalette::ToolTipText, Qt::white);
darkPalette.setColor(QPalette::Text, Qt::white);
