D3D11: Fixed SDL_RenderDrawPoints() ignoring input after the first 128 points.

If a limit would be needed then count should be adapted before stack allocation.

Android: Added missing import statement.

It did not compile without.

Fix some Android keyboards that didn't work properly.

This conversation came from Joshua Granick on Twitter, starting here:

"We found an issue where certain Android keyboards (like the S6 with
predictive text) wouldn't work ... Certain keyboards use a predictive text
mode that does not dispatch a traditional onKey events, which is troublesome
... but telling the OS to use a "visible password" keyboard helps deal with
this problem ... perhaps there's some other way (onKeyPreIme?) to do
"textediting" events, but for now, this should be a fast fix ...
I hear it affects the Galaxy Tab A 8.0", Galaxy S6, Asus ZenPhone 2, maybe
others"

Added SDL_JoystickCurrentPowerLevel() to WhatsNew.txt for 2.0.4.

Fixed freeing uninitialized pointers on failure cleanup in tests.

Android: Added a new method in SDLSurface.

Android: Added new key codes without mapping.

Converted tabs to spaces for SDL style

Fixed sending a size event while setting up a window (fix for DOTA 2 on Source 2)

Mac: Reset display if going from fullscreen to a fullscreen Space or vice-versa.

Otherwise, bad things happen.
