This worked in 2.0.5 as normal, but stopped working in 2.0.7. The monitor's resolution doesn't change, a window is created in full screen mode at the virtual desktop resolution instead.
The EGL_GL_COLORSPACE_KHR is an attribute for eglCreate*Surface.
As written in EGL_KHR_gl_colorspace documentation:
Accepted as an attribute name by eglCreateWindowSurface,
eglCreatePbufferSurface and eglCreatePixmapSurface
EGL_GL_COLORSPACE_KHR 0x309D
(...)
A future SDL release will change the borderless window to act more like a normal window that happens to have no chrome, to support windows that draw their own chrome. In the meantime, those applications should set the "SDL_BORDERLESS_WINDOWED_STYLE" hint.

As a new year gift I have implemented the Windows version of SDL_GetWindowBordersSize(). I needed it for auto-selecting a cozy window size for the game I'm currently working on and noticed that it only worked under X11, so I thought it could be a good excuse to contribute back more stuff. The Mercurial patch is attached as a .diff file. Let me know what you think.
Happy 2018 to all the SDL2 devs and users!

PS: Keep in mind that Windows 10 includes the 8px invisible grip borders as part of the frame. There's a way of detecting if Aero/DWM is being used and ask only for the visible rect, but I believe that GetWindowRect() is doing that for a reason and working as intended, so I haven't changed it. (See [2])

- Use a single buffer for various non-changing constants accessed by the GPU, instead of multiple buffers.
- Do the half-pixel offset for points and lines using a transform matrix so we don't need a malloc when rendering.
- Don't add a half-pixel offset for other primitives and textures. This matches D3D and GL render behaviour.
- Remove the half-texel texture coordinate offset since it's not needed now that there's no more half-pixel position offset when rendering a texture.
- Don't try to set texture usage on iOS 8 since it doesn't exist there.
"GetVersionExA is deprecated in windows 8.1 and above's SDK, causing a warning
when building against the win10 SDK. Attached patch cleans up the usage for a
warning-free build.
GetVersionExA was being used to test to see if SDL was running on win9x or
winnt. A quick chat with Ryan on twitter suggested that SDL doesn't
officially support win9x anymore, so the call to this can be outright removed.
As an aside, replacing the call to GetVersionExA with VerifyVersionInfoA (the
recommended path) would have been pointless, as VerifyVersionInfoA only
supports VER_PLATFORM_WIN32_NT and doesn't officially support any other value
for dwPlatformId currently. (And it's probable that win9x SDKs didn't have
VerifyVersionInfo* in them anyway.)"
Fixes Bugzilla #4019.
