CRT shader by Timothy Lottes

	//
	// PUBLIC DOMAIN CRT STYLED SCAN-LINE SHADER
	//
	// by Timothy Lottes
	//
	// This is more along the style of a really good CGA arcade monitor.
	// With RGB inputs instead of NTSC.
	// The shadow mask example has the mask rotated 90 degrees for less chromatic aberration.
	//
	// Left it unoptimized to show the theory behind the algorithm.

equalent / Qt 5 Dark Fusion Palette

Created February 3, 2020 23:56 — forked from QuantumCD/Qt 5 Dark Fusion Palette

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);

Aligned memory allocation

	// We require whatever user asked for PLUS space for a pointer
	// PLUS space to align pointer as per alignment requirement
	void mem = malloc(size + sizeof(void) + (ALIGN - 1));

	// Location that we will return to user
