Draw points can accept multiple colors. Draw points now uses vbos. Allowed the user to set the usage hint for the VBO. When changing data in a vbo, the data will be orphaned if the mode is not Fixed.
Josh's Graphics Library
Yet Another C++ Rendering Toolkit
Features
- Modern C++ (20).
- Cross Platform (Linux & Windows 10 1909 or newer).
- Provides single-function-calls to render various graphics in 2D and 3D.
- Integrates right into an existing OpenGL rendering system.
- Quick Rendering of Text, Shapes, Sprites / Textures, etc.
- High-performance text rendering.
- Little-to-no overhead.

Usage
// Makes sure the glViewport will be the correct size.
// Typically done once per frame.
JGL::Update(window_size);
JGL::J2D::Begin();
JGL::J2D::FillRect(Colors::Blue, {0,0}, {16,16});
JGL::J2D::End();
// See the example program in main.cpp for more in-depth usage.
Requirements
An OpenGL 2.1 or newer accelerator with at-least two texture mappers that supports the GL_ARB_framebuffer_object extension or
an implementation that can provide those features through alternative means (common on ArmSoC and Risc-V).
