[Issue Report]: SDL_RenderSetIntegerScale() is required but not avalible in SDL 2.0.3

[AJenbo]

Operating System

Mac PPC

DevilutionX version

1.5.3

Describe

We support SDL 2.0.3 but when trying to build you get an error regarding SDL_RenderSetIntegerScale() not being found.

To Reproduce

Find an old version of SDL2, try to compile

Expected Behavior

No response

Additional context

No response

Ah, that function is only available since SDL 2.0.5, so we should guard against that
Or perhaps just say that we require 2.0.5+

[AJenbo]

I'm ok with either. We could just hide the interger scale option on older SDL. PPC Mac has SDL 1.2.15 and 2.0.3. And so fare it feels like the SDL 1.2 port works better (but since I have only tested DevilutionX 1.0.3 not many features where available).

We already turn it off when SDL1.2 is in use.

[AJenbo]

Looks like SDL_GetDisplayDPI and SDL_SetWindowResizable() are in a similar situation

[glebm]

Let's see if the latest SDL2 works on 10.4 ppc mac with macports.
If that works, we can simply bump the requirement.

Might take a week to find out, things are very slow to build

[AJenbo]

The fact that if you click in the upper right corner you hit the OS search bar makes the SDL2 that is in tigerbrew really undesirable any way.
