really need to replace that fallback with my software renderer.

// This is actually slightly imperfect: the SDL_Texture side of things uses alpha, not a colour-key,
// so the bug where the font is blended with the colour key doesn't occur. SDL_Textures don't support
// colour-keys, so the next best thing is relying on the software fallback, but I don't like the idea
// of uploading textures to the GPU every time a glyph is drawn.
