Implement remaining SFML 2.6.0 changes

[ChrisThrasher]

Credit to @dogunbound for this list from PR #186. I'm moving this list out to its own issue so we can track these changes while we incrementally merge PRs.

---

Basically, we need to slowly go through EVERY pull request and see if any change needs to be made and make those changes. If there aren't any changes needed for a specific pull request, mark it as complete.

The most work lies in the SFML patches that add new features so I'll try to list them out here. This should make it easier to understand what work remains and start delegating that to those who volunteer. This is mostly just an inverse of the above list.

I'm checking off items as soon as a PR to fix them is open. After that the PRs themselves will track our progress.

• Allow creation of a window without an OpenGL context SFML#1484
• Add support for creating Vulkan window surfaces. SFML#1557
• Scancode SFML#1235
• Add support for colored cursors in Unix implementation SFML#1694
• Added support for directional arrow resize cursors on Linux SFML#1688
• DRM/KMS Implementation SFML#2029
• Added getPosition() and getSize() to sf::Rect<T>. SFML#1047
• Implemented saveToMemory and saveImageToMemory. SFML#1669
• Add Min and Max blend modes SFML#1756
• Added auto hinting compensation to fix too wide gaps between small glyphs SFML#1746
• Support sRGB color space in RenderTexture SFML#1757
• Adjustable processing interval in SoundStream #1517 SFML#1666 (no changes required)
• MP3 reader support using minimp3 SFML#1851

I would Highly recommend you put up a draft Pull request of the one you are working on, so others don't accidentally "take" yours.

I'll set up a PR later and update this comment with said PR number. I also just realized you can't really make a PR without a change, so calling dibs here first would be best.

I'm marking SFML/SFML#1666 as complete since using sf::SoundStream::setProcessingInterval requires inheriting from sf::SoundStream and since that is not something we can express in the C interface, I'm not sure it makes sense to add that to CSFML. I suppose we could make a function called sfSoundStream_setProcessingInterval but then we're taking a protected function and basically making it public which doesn't seem quite right.

I also considered adding it to sfMusic but protected member functions can never be promoted to public member functions so this is not something we can call on an instance of sf::Music and thus compilation fails.
