[lazarus] Resize crash

[Shane Miller]

The crash was caused by the creation of the SendMessage3 procedure and the removal of the LM_CREATE message in SendMessage2.  The canvas was being created in SendMessage2 yet.

In SendMEssage3, we cxurrently are sending it a TControl.  I am going to change it to TObject because TControlCanvas is not derived from a TControl and therefore can't be sent as one.

Cool.. We just commented out the code so that the canvas was not
overpainting the menu items. It was causing some confusion.

I do not know how the menu bar is going to respond to the size changes
because no default alignment method is set in the menubar constructor. If
you look in TButton I set a default alignment in the TButton contructor to
alNone. Stuff like the menu bar should be set to alTop as the default
alignment method.

Cliff, the reason the mainfor crashes when you resize it is because it
throws a DRAW event and in Main.PP I was testing the TCanvas fillrect and I
write to it.  Of course, it's commented out so it crashes.

I will fix it and re-submit the changes to CVS
