So all we did with the surface in SDL1 was split into window, surface, renderer and texture. Instead of drawing into the surface and then flipping, you build your pixels, then update a texture and then copy the texture to the renderer. Here we use an empty RGB surface to hold our pixels, which enables us to keep most of the code the same. The SDL1 code has been adjusted to refer to "surface" instead of "window" when trying to access the properties of the surface. This approaches the configuration by adding a new --enable-grub-emu-sdl2 argument. If set to yes, or auto detected, it disables SDL1 support automatically. This duplicates the sdl module block in Makefile.core.def which may be something to be aware of, but we also don't want to build separate module.

See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. See the file MAINTAINERS for information about the GRUB maintainers, etc. If you found a security vulnerability in the GRUB please check the SECURITY file to get more information how to properly report this kind of bugs to the maintainers. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
