- Fix coordinate system for 1:1 pixel mapping (was using nm scale)
- Set worldUnitLength to 1/96 to match native test setup
- Add SetLookAtPoint and SetZoomFactor for proper view transformation
- Fix glDrawBuffers for WebGL 2.0 (array index must match attachment)
- Add legacy_gl_stubs.js for wxWidgets compatibility
- Add isReady() check to prevent race condition in Playwright tests
All 28 GAL test scenarios now render correctly in WebGL.
