Dep on //printing in //ui/qt if printing is enabled
|
||||
|
||||
qt_ui.h can use printing/printing_context_linux.h, and needs to dep
|
||||
on //printing if it does, to avoid a missing dependency build break.
|
||||
|
||||
Without this fix, a clean build can fail on obj/ui/qt/qt/qt_ui.o with

[QT] Account for logical scale factor
|
||||
|
||||
Previously we were only using the device pixel ratio. But QT UI
|
||||
scales with both the device pixel ratio and the logical DPI. This CL
|
||||
sets Chrome's scale factor to be the product of these two.
