public Statistics getStatistics()
Renderer
The statistics allow tracking of how data
per frame, such as number of objects rendered, number of triangles, etc.
These are updated when the Renderer's methods are used, make sure
to call Statistics.clearFrame()
at the appropriate time
to get accurate info per frame.

When alpha coverage and multi-sampling is enabled, each pixel will contain alpha coverage in all of its subsamples, which is then combined when other future alpha-blended objects are rendered.

The shader which is currently set with setShader
is
responsible for transforming the input vertices into clip space
and shading it based on the given vertex attributes.
The integer variable gl_InstanceID can be used to access the current
instance of the mesh being rendered inside the vertex shader.
If the instance data is non-null, then it is submitted as a
per-instance vertex attribute to the shader.renderMesh

Renderer
If enabled, color values rendered to the main framebuffer undergo linear -> sRGB conversion.
This is identical to FrameBuffer.setSrgb(boolean)
except it is toggled
for the main framebuffer instead of an offscreen buffer.
This should be set together with Renderer.setLinearizeSrgbImages(boolean)
As a shorthand, the user can set AppSettings.setGammaCorrection(boolean)
to true
to toggle both Renderer.setLinearizeSrgbImages(boolean)
and
Renderer.setMainFrameBufferSrgb(boolean)
if the
Caps.Srgb
is supported by the GPU.

- Image.Format.Luminance8Alpha8
- Image.Format.DXT1
- Image.Format.DXT1A

For all other formats, no conversion is performed.
If this option is toggled at runtime, textures must be reloaded for the change to take effect.
