SDL_RenderSetClipRect() calls into renderer->UpdateClipRect(renderer).
I am not sure if UpdateClipRect() can point to a number of clip rect update functions, but on my platform it calls D3D_UpdateClipRect().
In that function, the rect to pass to IDirect3DDevice9_SetScissorRect() has it's right field set as:
r.right = rect->w + rect->w;
But actually, this should be:
r.right = rect->x + rect->w;
This lets us change things like this...
if (Failed) {
SDL_SetError("We failed");
return -1;
}
...into this...
if (Failed) {
return SDL_SetError("We failed");
}
Fixes Bugzilla #1778.

I have investigated the warning "Failed loading D3DX9_*.dll" and come up with the enclosed patch (please forward it to relevant SDL2 mailing list/bugtracker).

static void
D3D_DestroyRenderer(SDL_Renderer * renderer)
has a critical problem. It may try to release IDirect3DSurface9 surface pointed
by NULL pointer. That leads to really wierd consequences on my system.
It happens when the previous call to IDirect3D9_CreateDevice() fails leaving
D3D_RenderData::defaultRenderTarget uninitialized.

RenderTarget has to be released before a device reset is done. It's a
D3DPOOL_DEFAULT surface (resides in video memory and have to be recreated).
- Added new SDL_HINT_ALLOW_TOPMOST hint, when set to "0" then never set the topmost bit on a window. Useful when debugging fullscreen issues.
- fixed crash in windows joystick scanning if we failed to load the xinput dll
- added support for SDL_WINDOW_FULLSCREEN_DESKTOP under windows
- synthesize relative mouse movements if directinput fails to send relative moves, happens under virtual box.

Direct3D renderer should set D3DCREATE_FPU_PRESERVE for not behaving vastly
different to OpenGL/software rendering on doubles and break some libraries
really badly.
Most notable affected example: Lua, which does the most unpredictable things
which are really almost impossible to debug/find out for beginners who never
heard this culprit exists.
Since I believe all renderers should behave the same on that doubles simply
work as expected in a program, this should really be changed! (also this wasted
a few days of my life wondering why everything in my program was so broken)
The render viewport is automatically re-centered when the window changes size, so applications that don't care will not have to handle recalculating their rendering coordinates.
Fixed API for drawing and filling multiple rectangles - the parameter should be an array of rects, not an array of pointers to rects.
Fixed API for updating window rects for consistency with other APIs - the order is pointer to array followed by count in array.
The software renderer has been re-routed to use the framebuffer interface, which makes it possible to have software rendering available even on simple ports.
