* Clearly comment
* fixup
* This is to ensure the RenderTexture internal texture2D PMA flag is set to the correct value.
[CCSprite.cpp] Blending mode needs to be set based on the PMA flag of the texture if using Sprite::initWithTexture().
* [CCSprite.cpp] Removed redundant code related to blending mode and opacityModifyRGB when creating a sprite with a texture.
* [BugFix] fix compile error
* [Feature] fix spirte, label test when EGL context lost
* [Feature] map uniform location
* [Feature] remove unneeded codes
* [Feature] add BufferManager
* [Feature] fix compile error
* [Feature] add files
* [Feature] remove unneeded codes
* [Feature] no need to release opengl resource
* [Feature] update BufferManager
* 1. reCreate frame buffer when needed.
2. initial texture when come back to foreground
* [Feature] add Program and Buffer event listener
* [FixTerrain] need check location had used before
* fix compile error
* add updateTextureDescrptor function for TextureMTL, since TextureMTL creation was move to Texture2D constructor.
* [FixDrawNode] record buffer data when needed
* [FixShaderTest] add nullptr judgement
* [FixShaderText] no need to reCreate ProgramState when come back to foreground
* [FixRenderTexture] retain the render texture image
* [Feature] optimize buffer memory
* fix compile error
* fix CI test fail
