描述

Originally reported by: Daniel Pope (Bitbucket: lordmauve, GitHub: lordmauve)

On high resolution displays, Pygame games designed for low dpi displays come out incredibly tiny. We should detect such displays and apply suitable scaling.

Pygame_sdl2 has some support for high dpi displays though it looks like this just returns a larger surface corresponding to the physical display. We would need to honour the WIDTH and HEIGHT attributes in the game and upscale before painting the screen.

This may be slow, so we could look at doing the upscaling in hardware (eg. with Pixel Buffer Objects or Buffer Object Streaming).

研究方向
Investigate pygame sdl2's highdpi support to understand how to detect high DPI displays. Look at pgzero's screen module to see how surfaces are created and blitted. Consider implementing a scaling layer that multiplies game dimensions by the device pixel ratio. For performance, explore using OpenGL pixel buffer objects or buffer object streaming to upscale the screen surface. The maintainers may have additional insights in the linked Bitbucket issue.
