We will draw into a buffer texture to allow easy resolution changes
It will also make it easier to apply screen transitions and similar effects later
When using pygame._sdl2.video you do not call pygame.display.setmode()
Therefore calling surface.convert() or surface.convert_alpha() will throw an error
When you create a Texture that needs alpha blending you must set its blend mode
Alpha blending will be set automatically when loading from an image with transparency, such as PNG
Remember to use the buffer size instead of the window size when drawing onto the offscreen buffer
This will allow you to scale the screen to any window or fullscreen desktop size

Font features in pygame are design for blitting to a surface, not for GPU rendering
It is possible to create a streaming texture and then using texture.update() to update the texture
from a pygame surface, but accessing GPU memory is slow and this should be done sparingly.
Therefore I created a simple TextureFont class. We will use the animation feature of this class
for a little extra fun. We will also create some sprites and let them animate too.
Also, for this example we use a Character class to move and rotate individual characters across
the screen. This is very similar to how you will handle sprites later.
