How to fix a canvas so it will look good on retina/high-DPI screens.
/*
UPDATED for 2023 - Now much simpler. The old tricks are no longer needed.
The following code makes an 800×600 canvas that is always as sharp as possible for the device.
You still draw on it as if it's the logical size (800×600 in this case), but everything just
looks sharper on high-DPI screens. Regular non-sharp screens are not affected.

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?
