This commit adds the `glFramebufferTextureMultisampleMultiviewOVR`
function, enabling MSAA to work in conjunction with the multiview
extension.
The function's declaration is present in the latest main branch of the
Khronos GLES2 API headers. While directly pulling these updated headers
is the ideal approach, it would necessitate a significant reorganization
of Filament's current header file structure and incorporate more files
than currently needed.
To minimize immediate changes and limit scope, this change adopts
only the necessary function declaration by copying it directly.
BUGS=[417311684]
Some clients need to link against both Filament and OpenGL. This can lead to symbol clashes under certain circumstances. As a fix, prefix all of our `bluegl` symbols with `bluegl_`. Previously we made this naming change for Windows, but now we'll do it on all platforms for simplicity.
* Improve rendering to TextureView
UiHelper wasn't calling the resize callback at init time when attaching
to a TextureView, but it was for a SurfaceView. This makes both code
paths consistent and fixes the standard samples if they are modified to
render to a TextureView.
This change also adds a new sample app that shows how to render into
a TextureView.
