Suppress warnings for deprecated Cursor constructor

[ShahzaibIbrahim]

Cursor(Device, ImageData, ImageData, int, int) was deprecated recently which is still used in some of the snippets testing that exact constructor. That's why the warnings are being suppressed.

Would you please migrate the snippets to the new way ? This is the place where people using SWT should come to see how things are used so showing them these deprecated APIs is counterproductive.

@akurtakov we recently implemented Snippet386 covering all kind of Cursors. Also Snippet92 was to show how this specific cursor with source and mask should work. We either remove it completely but I don't see the reason to migrate it to new way since we already have example in Snippet386 for others.

I'm with Alex on this one: why show the deprecated constructor in the snippets in the first place? It's not like we want new users to learn how to use a deprecated constructor.

Instead, I would:

• Remove the 1st option (usage of deprecated constructor) from Snippet386
• Delete Snippet92

One other detail: I just noticed that there is no explanation as to why has the constructor been deprecated (no linked GH issue either). That would be a nice addition to the JavaDocs, don't you think?

To answer my own question: there's the commit message

... so we're good, no more "nice additions" required :-)

Snippet92 may be migrated by integrating the mask data into the the source image data. The it would still reflect the source + mask use case.

For Snippet386 it does not really make sense to migrate something as that snippet shows the behavior of all constructors in comparison. And in my opinion it's still valuable to the deprecated constructor in there in case someone wants to compare those behaviors, e.g., because they still use separate image and mask files and want to compare differences or the like.

I would then like to remove the Snippet92 completely. Since we have enough (~3) snippets covering how the constructor with source data only works.

Okay, can you please point to the one that shows how to create cursor with source + mask based on the single-ImageData constructor?

In Snippet119, reflecting source + mask based on the single-ImageData constructor.

See,

eclipse.platform.swt/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet119.java

Lines 80 to 91 in 6fa4ee7

	ImageData sourceData = new ImageData (16, 16, 4, palette, 1, srcData);
	//Create a mask ImageData of depth 1 (monochrome)
	palette = new PaletteData (black.getRGB(), white.getRGB());
	ImageData maskData = new ImageData (16, 16, 1, palette, 1, mskData);
	//Set mask
	sourceData.maskData = maskData.data;
	sourceData.maskPad = maskData.scanlinePad;
	//Create cursor
	Cursor cursor = new Cursor(display, sourceData, 10, 10);

Thank you! Then I would be fine with removing the snippet.

[ShahzaibIbrahim]

@HeikoKlare I have deleted the snippet. This PR is ready for review.

[HeikoKlare]

Please also remove references to the snippet, in particular the ones in the Snippets.md.

[akurtakov]

Please remove the snippet from

Thank you. Looks fine now.
