    @brief A powerful OpenGL-based graphics library written in C99.

    ----------------------------------------------------------------------------
    Licensing information at end of header
    ----------------------------------------------------------------------------

    Features:
    ---------
    - Written in C99
    - Single header library for easy build system integration
    - Embeds GLAD for seamless OpenGL function loading
    - Simple texture and shader creation
    - Default shader and uniforms
    - Rendering of dynamic vertex arrays and static vertex buffers
    - Render to texture
    - Simplified shader uniform setters
    - State stack
    - Simple and concise API
    - Permissive license (zlib or public domain)

    Summary:
    --------

    This library is an advanced 2D renderer built on top of OpenGL. It currently
    supports OpenGL 3.0+ and OpenGL ES 3+ as well.

    The basic workflow is to initialize the library, create a context, load any
    shaders and/or textures needed, specify some geometry (vertices) and draw
    the buffer or array of vertices. A vertex consists of position, color, and
    uv coordinates.

    There is a default shader that makes sensible assumptions about how vertices
    and textures will be used. It is likely to be sufficient unless performing
    advanced VFX.

    The default shader exposes two uniform variables: 1) a projection matrix;
    and 2) an affine transformation matrix. These two matrices are multipled
    together to form the mapping from vertices to the screen.

    State including blend mode, the projection and transform matrices, and
    the viewport parameters are managed using the state stack. This enables
    state changes to be isolated. Push the current state on the top of the
    stack, make some local changes, and pop the stack to restore the original
    state.

    Uniforms can be set using a simple, fast, and concise API.

    Please see the examples for more details.

    To use this library in your project, add

    > #define PICO_GL_IMPLEMENTATION
    > #include "pico_gl.h"

    to a source file.

    Constants:
    --------

    - PICO_GL_UNIFORM_NAME_LENGTH (default: 32)
    - PICO_GL_MAX_UNIFORMS (default: 32)
    - PICO_GL_MAX_STATES (default: 32)

    Must be defined before PICO_GL_IMPLEMENTATION

    Todo:
    -----
    - MSAA flag for examples
    - Better version handling
    - Shader examples
    - Scissor
    - Indexed buffers
    - Multiple texture units
