Minor improvement of the desktop file
Core: Remove the ratio parameter in Zelda UCode's SizeForResampling func

It's only ever passed PB.RatioInt
CFrame: Handle close events that can't be vetoed.

This can happen during shutdown.

As long as we don't call event.Skip() the CFrame won't be closed yet, so even if we can't veto the shutdown will still happen in the correct order.
Fix a cast warning when compiling with MSVC

Would previously give a C4800 warning.
CFrame: Add fullscreen window styles to enable exclusive mode in OpenGL.

This is not implemented within the backend, but relies purely on driver heuristics.
CFrame: Always exit fullscreen before showing the stop dialog.
Core: Default initialize a pointer to nullptr in gdsp_do_dma()

The if-statement implies that this could fail in the switch statement somehow. If it does fail, then we'd be comparing with an uninitialized pointer.
x64Emitter: optimize immediate sizes

A nice alternative than trying to do it throughout the JIT.
Changed toolbar to be static, increasing UI integration
Core: Fix two more potential memory leaks within IOdarwin.mm
Common: Use the OSX equivalent byte-swap functions
Switch play/pause button icons when necessary
Allow toggling the toolbar in the menu
Included toolbar headers, preventing forward-decl errors
Core: Kill off Host_UpdateBreakPointView()

Uses wxWidgets event propagation to the parent window which then appropriately handles the breakpoint list updating.
UnitTests: Get rid of now-nonexistent Host_GetInstance() within StubHost
Core: Kill off Host_UpdateLogDisplay()

This was actually never used as far as I can tell. There was no wx event handling done whatsoever for the global ID, So this is basically a dead function.
D3D: Remove an unnecessary call to Host_GetRenderWindowSize()
WGL: Get rid of the use of the Host_GetRenderWindowSize() call.

Just use the Windows API to accomplish the same thing (this is what is done in Update()).

This makes the backing window handle the correct data-type for Windows for easier use in function calls.
AGL: Remove the call to Host_GetRenderWindowSize().

Just uses platform-specific ways to do the same thing.
