Revert "Fix screenshot functionality in fullscreen in SDL2"

Browse source 
This reverts commit 121fcd8369.

The reason I am reverting this is because the last commit actually fixes the *old* screenshot functionality, as the screen is being drawn back onto the buffer after they're swapped in the "real" size. Meaning the old function actually works perfectly fine now.

// Sryder: SDL2 uses borderless fullscreen mode, and creates a screen texture to upscale to the screen size.
// This breaks screenshots because the code here takes a screenshot of just the resolution from the bottom
// left corner, while the "true" resolution is the monitor resolution. We can either take a screenshot of
// the true resolution or just use the already made screen texture
// NOTE: The SDL1.2 version should get a return of false from ReadScreenTexture as no screen texture will have
// been made, this will also mean that if the screen texture doesn't exist for some reason it will fall
// back to the old version
