Improve Bloom

[dmnsgn]

• add tint color
• anamorphic ratio
• lens dirt
• pack bloom intensity in bloom texture alpha for selective bloom

[vorg]

• combine 8 upscale passes adding all blur steps into threshold texture into one final blend pass

Should we also add a blending mode option for this (if we want to blend with screen for instance)?

[vorg]

if we can make it work, then yes.

[dmnsgn]

• use bicubic sampling for smooth bloom
• or use mipmaps directly (WebGL2) instead of rendering to 8 textures

Are we using Kawase technique here? Very good video on modern bloom that talks about downsampling but also upsampling instead of just blending https://www.youtube.com/watch?v=ml-5OGZC7vE

No, our downsample is 4x4 box filter (+Karis's luma weighted average). No Kuwase, no 13 taps.
