Add CezveRender to awesome-java-ui

[Copilot]

Onboards CezveRender — a real-time 3D renderer built from scratch in Java 17+ using OpenGL 3.3 and LWJGL.

Changes

• cezverender.md — Front matter + description covering the rendering pipeline (shadow mapping, Phong shading, OBJ loading via Assimp, ImGui runtime editor); tagged Game Development + Desktop UI; status Experimental (personal learning project, no formal releases)
• images/ui-cezverender.png — 1280×720 screenshot from the project's scene demo
• images/thumbnail-cezverender.png — Auto-generated thumbnail via GenerateThumbnails.java

Code Example

Demonstrates CezveRender-style shader setup using LWJGL/OpenGL 3.3, including compile and link error checking:

public ShaderProgram(String vertexSrc, String fragmentSrc) {
    int vertShader = compileShader(GL_VERTEX_SHADER, vertexSrc);
    int fragShader = compileShader(GL_FRAGMENT_SHADER, fragmentSrc);

    programId = glCreateProgram();
    glAttachShader(programId, vertShader);
    glAttachShader(programId, fragShader);
    glLinkProgram(programId);
    if (glGetProgrami(programId, GL_LINK_STATUS) == GL_FALSE) {
        throw new RuntimeException("Program link error: " + glGetProgramInfoLog(programId));
    }
    ...
}
