If user doesnt specify a format_modifier explicitly, then use GetFB2
to identify the format_modifier of the framebuffer being grabbed.
This is supported on newer linux builds, where xf86drmMode.h has
added support for GetFB2.

Verify that the source and destination pixformats are supported by
fbtile before detiling the source into destination.

If the framebuffer is a tiled layout, use the fbtile helper routines
to try and detile it into linear layout, if supported by fbtile.
It uses the format_modifier associated with the framebuffer to decide
whether to apply detiling or not and inturn which specific detiling
to apply.
If user is usin
Added logic to support detiling of framebuffer.
By default this is disabled. Only if requested by the user, the
logic will be triggered.
It uses the fbtile helper routines to do the detiling. Currently
32bit RGB pixel format based framebuffers are supported.
