Major refactoring to remove ALL legacy OpenGL immediate mode calls from WEBGL_GAL and replace them with WebGL 2.0/OpenGL ES 3.0 compatible code. Key changes: - Add MVP matrix uniform support (replaces glMatrixMode/glOrtho/glLoadMatrix) - Add matrix math helpers (computeOrthoMatrix, multiplyMatrix4x4, etc.) - Replace glBegin/glEnd/glVertex with vertex manager pattern - Rewrite DrawCursor to use vertex manager and DrawLine() calls - Rewrite DrawBitmap to use vertex manager with SHADER_FONT mode - Replace glEnableClientState with glVertexAttribPointer - Replace glDrawBuffer with glDrawBuffers (WebGL 2.0 API) - Add fullscreen_quad.cpp/h for compositor Present() - Update SHADER class with mat4 uniform support - Add MultiplyMatrix() to vertex_manager for Transform() - Remove all legacy GL stubs from wasm_stubs.cpp Build now completes with FULL_ES3 mode (no LEGACY_GL_EMULATION). Remaining issue: wxWidgets GL library calls glColor3f internally. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
