SDL_GL_GetDrawableSize was introduced after 2.0.0, so we need to check for that version before we call this method. Fixes MethodNotFounException on vanilla libsdl2-2.0.0 on linux.
Using msbuild/xbuild wildcards results in different behavior between the two implementations. Since we require 7z anyway, it is simpler if we just use that directly.
The debug.log would be deleted after launching an example, causing the
example browser to complain that the file cannot be found. In reality,
it should be deleted before launching an example - fixed.
When HiDPI is enabled, the size of the OpenGL surface (specified in
pixels) may no longer correspond to the size of the window (specified
in points). Width, Height, ClientSize and ClientRectangle return the
size of the OpenGL surface in device-dependent pixel coordinates
(origin: top-left pixel of the surface). Bounds and Size return the
size of the window in device-independent point coordinates (origin:
desktop).
This significantly improves the usability of keyboard input, by allowing
a common input scheme to be used on different keyboard layouts. Text
input will be facilitated through a new API.
The support burden for Windows versions prior to XP was too large, plus
the relevant code was completely untested. Removing that will allow us
to focus on the things that really matter.
Starting with OpenGL 4.1 and the ARB_ES2_compatibility extension, desktop contexts can execute OpenGL|ES code. This fallback will allow platforms to execute OpenGL|ES code even if EGL is not available (e.g. Nvidia/Windows).
Some drivers / operating systems export ES entry points as extensions on regular "desktop" GraphicsContexts. Attempt to load them even if the user has not explicitly asked for an ES context.
If SDL2 is supported, the PlatformFactory will now use it for creating the OpenGL ES context. Previously, it would revert to the native drivers when GraphicsContextFlag.Embedded was specified.
MouseMove no longer leaves the window borders when the cursor is
invisible. MouseButtonUp events are now reported even when they occur
outside the window. This aligns SDL2 behavior with the native drivers.
SDL_GL_MakeCurrent(IntPtr.Zero, IntPtr.Zero) is the correct way to
remove the current OpenGL context from the calling thread. Fixes
threaded rendering on Windows.
