Valid value of AX_GLES_PROFILE: 0, 200, 300
By default, the AX_GLES_PROFILE is:
- android: 200, allow axmol apps runs on: API 17 Android 4.2+ devices
- winuwp: 300
- Win32/linux/osx/ios/tvos: 0
For ios/tvos, will forcing AX_GLES_PROFILE to 300 if AX_GLES_PROFILE not 0
1. Rename uniformId to batchId, refine batch draw check logic, not use xxhash to compute uniforms id
2. Material works, not check all cpp-tests, but some 2d/3d material works fine
3. Shader load/cache API improvements.
4. BREAK compatibliity: Node::setProgramState change parameter needsRetain to ownPS and value inverted.
5. custom vertexLayout setup: add new API ProgramState::getMutableVertexLayout, mark ProgramState::setVertexAttrib deprecated.
6. ProgramManager registerCustomProgram change to gen progId by vsName, fsName
with xxhash64, if register succed, user can load it by progId with `loadProgram`
7. Add API ProgramManager::loadProgram for loading builtin by progType or
loding a custom program by id
8. Add API ProgramManager::loadProgram to load program by vsName, fsName
immediately without register as CUSTOM_PROGRAM
9. Add API Node::setProgramStateByProgramId(progTypeOrId); for set programState with
programType or programId explicit.
10. Migrate material load logic
In order to allow unity builds we need to avoiding "using namespace"
at file scope, #undef our file-specific #defines, and avoid having
static functions with identical name and signature.
