Issue 260529: IME UI is not placed at proper position when HiDPI is enabled

Reported by, Jul 16 2013 Project Member

Issue description

Version: 30.0.1565.0 canary
OS: Windows 8.1 preview

What steps will reproduce the problem?
1. Set OS DPI settings to 150%
2. Install Chrome canary
3. Launch Chrome canary with --high-dpi-support=1 launch option
4. Focus in Omnibox
5. Turn on MS-IME Japanese
6. Type "こんに"

What is the expected output? What do you see instead?

Suggestion UI / candidate window are placed at improper position actually.
It should be placed at proper position even under HiDPI environment.

Please use labels and text to provide additional information.

This is reproducible with Google Japanese Input. So seems that Chrome-side issue.
I think we should fix this issue in M30 release cycle as  Issue 149881  is now fixed seems that M30 will support HiDPI on Windows.

Changed paths:

Treats the returned value from ui::TextInputClient as DIP

On Windows, the returned value from ui::TextInputClient as DIP is supposed to be DIP (Density Independent Pixel). This CL adds relevant coordinate conversion so that IME UI can be placed at the proper position when  HiDPI is enabled on Windows.

This CL does not cover Win8 (Ash) mode.

BUG= 260529 ,  360334 
TEST=Manually tested on Windows 8.1 w/ and w/o HiDPI is enabled.
