Method Surface

src/Engine/Surface.cpp:137–157

* Sets up a blank 8bpp surface with the specified size and position, * with pure black as the transparent color. * @note Surfaces don't have to fill the whole size since their * background is transparent, specially subclasses with their own * drawing logic, so it just covers the maximum drawing area. * @param width Width in pixels. * @param height Height in pixels. * @param x X position in

 * @param bpp Bits-per-pixel depth.
