Jonas Ådahl	da3baba980	backend/native: Only disable KMS modifiers for i915 ... The intel DRM driver is known for not being able to handle multi head setups when KMS modifiers are enabled, due to the implicitly selected modifiers, while being more suitable for single head setups, cause bandwidth issues when a certain number of monitor times resolution and refresh rate is configured. We don't yet support automatically finding a combination of modifiers that work, and have because of this disabled KMS modifiers unless the driver actually needs it. Lets flip this configuration the other way around, changing the current udev rule to decide wen to *disable* KMS modifier support, as it so that only the Intel driver has this problem, while on the other hand, there several drivers that requires modifiers to function at all.

Karol Herbst	9b9b912765	backends: force enable modifiers on tagged devices ... Some devices can't scanout to linear buffers directly as the hw is not capable of eg rendering into a linear depth buffer. Add code to force kms-modifiers on udev taged devices.
