[Lazarus] New high DPI features in 1.7

[info at voiceliveeditor.com]

Hi

Just got latest svn 53624, The change does indeed help in that the form in 
not resized.
However when I compile, I am getting
Project Raised exception class 'EREADError' with message,
error reading xxx.designtimedpi: unknow property:'DesignTimeDPI'

This is when compiled with or without debugger, and when app launched 
directly.

If I click ok/continue a few times; then application is auto terminated.







>> My forms load, then get scaled.
>> I have checked property of form and Scaled is unchecked False;
>> PixelsPerInch=72
>> DesignTimePPu=72
>>
>> The scaling makes my form hard to read and even harder to edit; I am

Does r53623 help you? Forms with Scaled=False shouldn't be automatically
scaled in designtime - that was obviously a mistake from myself.
