kkinnunen 973d92cf91 SampleApp: Remove SkWindow::setColorType
Remove SkWindow::setColorType, it is used wrong and inconsistently.

The color type is actually property of window backbuffer, used when the
window is painted with software. This is as opposed to a generic window
property that would affect all operation.

Similar to MSAA sample count for window GPU backbuffer, the bitmap
backbuffer color type should be a parameter of "attach" or "create
window" functions, should this property ever be added back.

The apps use the call wrong, setting the type as kRGBA_8888
or kBGRRA_8888 without no apparent rationale. These color types
are incorrect, as the raster surface can not work with these.

Reorganize the SkWindow::resize, since no change in SkWindow backbuffer size does not neccessarily mean that SkView would not need the call.

Do not show the sw backbuffer color type in SampleApp title, as
it does not really provide any information. On small screens,
kBGRA_8888_ColorType fills up the whole title.
