[Lazarus] Trunk compilation broken by changing StrikeThrough property name

[Bart]

Hi,

Revision 39879 introduced some compile-time conditionals in lazcanvas
(fixing a typo).

This part

  {$IF FPC_FULLVERSION>=20601} //changed in 2.6.2 and 2.7; remove when
FPC 2.6.2+ only is supported
  Font.StrikeThrough := AFont.StrikeThrough;
  {$ELSE}
  Font.StrikeTrough := AFont.StrikeTrough; //old version with typo
  {$ENDIF}
:

However it breaks building with 2.6.2RC1 since  it's fullversion = 20602


As a quick fix, can we change that to:

  {$IF (FPC_FULLVERSION<20600) or defined(lazcanvas_typo)} //changed
in 2.6.2 and 2.7; remove when FPC 2.6.2+ only is supported
  Font.StrikeTrough := AFont.StrikeTrough; //old version with typo
  {$ELSE}
  Font.StrikeThrough := AFont.StrikeThrough;
  {$ENDIF}

This will allow 2.6.2RC1 users to define lazcanvas_typo when building
Lazarus, as a temporary workaround.
