static-analysis shows numerous "performance-unnecessary-value-param" warnings in non-native theming code:
"the parameter 'aDpiRatio' is copied for each invocation but only used as a const reference; consider making it a const reference"

Per Phabricator review:
Yeah, I'm pretty sure we should just ignore that lint warning. https://godbolt.org/z/z3baf1 shows that on x64_64 we'll pass the DPIRatio value using a register, and when we have too many preceding arguments, we'll store the 32 bit float on the stack. With const DPIRatio& we're passing pointers around.
