Zooming in on maps

[langhillie]

For Nuke in particular, it would be nice if I could zoom in the 2d view a bit. 50% of the width are areas of the map that rarely have anyone in them (T and CT Spawn), and the rest of the map feels kind of cramped as a result.

That's a cool idea, but I think the sdl2-gfx library draws directly using the renderer.
Using the following functions we could maybe update the updateGraphics function like this:
https://pkg.go.dev/github.com/veandco/[email protected]/sdl#Renderer.GetRenderTarget
https://pkg.go.dev/github.com/veandco/[email protected]/sdl#Renderer.Copy

func (app *app) updateGraphics {
    Clear
    drawInfobars
    Copy Map
    Draw the things
    GetRenderTarget
    Copy (portion of the map we want to zoom in on, to the original map size)
    drawString("k shows hotkeys")
    Present
}
