* Improve performance when converting texture formats.
Still more work to do.
* Speed up buffer -> texture copies.
No longer copies byte by byte. Fast path when formats are identical.
* Fix a few things, 64 byte block fast copy.
* Spacing cleanup, unrelated change.
* Fix base offset calculation for region copies.
* Fix Linear -> BlockLinear
* Fix some nits. (part 1 of review feedback)
* Use a generic version of the Convert* functions rather than lambdas.
This is some real monkey's paw shit.
* Remove unnecessary span constructor.
* Revert "Use a generic version of the Convert* functions rather than lambdas."
This reverts commit aa43dcfbe8.
* Fix bug with rectangle destination writing, better rectangle calculation for linear textures.
Some parts of our code needs C# 8 who isn't set as default in Visual Studio. To fix this we have to set the C# version correctly in the csproj files and then we are be able to build the project using Visual Studio.
* Updated all NuGet packages to latest, and updated the framework from .NET Core 3.0 to 3.1.
* Updating appveyor settings for 3.1
Updating appveyor to use the netcoreapp3.1 path instead of 3.0.
* Removing unneeded NuGet package System.Runtime.CompilerServices.Unsafe.
* Removing unused NuGet package SharpFontCore.
* Removing unused NuGet package TimeZoneConverter.Posix
* Cleaning up by adding newline to a csproj.
* Simplfying a NuGet conditional include, and adding a warning disable for an annoying NuGet package.
* I'm not sure if .travis.yml is still used, but I'm updating its 'dotnet' version to the correct SDK.
* Making the runtime version into its own environment variable so it's a bit easier to change in the future.
* Removing OpenTK.NetStandard reference from Ryujinx.Common
* Fixing indentation in Common.csproj
* Updating the README to specify .NET Core 3.1.
* Reverting the update of the GTKSharp package so it doesn't block the PR.
