# You can comment out the code below if you do not want High

# Enabling High DPI support in app can be done by

# embedding a DPI awareness xml manifest in executable

# (see Issue 112 comment #2), or by calling SetProcessDpiAware

# function. Embedding xml manifest is the most reliable method.

# The downside of calling SetProcessDpiAware is that scrollbar

# in CEF browser is smaller than it should be. This is because

# DPI awareness was set too late, after the CEF dll was loaded.

# To fix that embed DPI awareness xml manifest in the .exe file.

# There is one bug when enabling High DPI support - fonts in

# javascript dialogs (alert) are tiny. However, you can implement

# custom javascript dialogs using JavascriptDialogHandler.

# Additionally you have to set "auto_zomming" application

# setting. High DPI support is available only on Windows.

# You may set auto_zooming to "system_dpi" and browser

# contents will be zoomed using OS DPI settings. On Win7

# these can be set in: Control Panel > Appearance and

# Personalization > Display.

# Example values for auto_zooming are:

# "system_dpi", "0.0" (96 DPI), "1.0" (120 DPI),

# "2.0" (144 DPI), "-1.0" (72 DPI)

# Numeric value means a zoom level.

# Example values that can be set in Win7 DPI settings:

# Smaller 100% (Default) = 96 DPI = 0.0 zoom level

# Medium 125% = 120 DPI = 1.0 zoom level

# Larger 150% = 144 DPI = 2.0 zoom level
