23 * # CategoryRender
24 *
25 * Header file for SDL 2D rendering functions.
26 *
27 * This API supports the following features:
28 *
29 * - single pixel points
30 * - single pixel lines
31 * - filled rectangles
32 * - texture images
33 * - 2D polygons
34 *
35 * The primitives may be drawn in opaque, blended, or additive modes.
36 *
37 * The texture images may be drawn in opaque, blended, or additive modes. They
38 * can have an additional color tint or alpha modulation applied to them, and
39 * may also be stretched with linear interpolation.
40 *
41 * This API is designed to accelerate simple 2D operations. You may want more
42 * functionality such as polygons and particle effects and in that case you
43 * should use SDL's OpenGL/Direct3D support, the SDL3 GPU API, or one of the
44 * many good 3D engines.
45 *
46 * These functions must be called from the main thread. See this bug for
47 * details: https://github.com/libsdl-org/SDL/issues/986

2581 * or scaling to adjust it, but it will be blurry.
2582 * - It uses a simple, hardcoded bitmap font. It does not allow different font
2583 * selections and it does not support truetype, for proper scaling.
2584 * - It does no word-wrapping and does not treat newline characters as a line
2585 * break. If the text goes out of the window, it's gone.
