14890	dynamic custom header image sizes patch	a.hoereth		"This patch adds the capability for theme developers to use maximum, fixed or automatic header image sizes.

HEADER_IMAGE_WIDTH and HEADER_IMAGE_HEIGHT can be set to 3 different states:
fixed - ""940"" - like the old feature. all images get resized to a fixed size
max - ""max:940"" - smaller images are not resized
auto - ""auto"" - no images are changed

At the moment the if clause handling if the image has to be resized and how is very complex. I can simplify it very easily, but didnt due to the possibility that we could at a ""manual/automatic cropping"" button or just change some conditions to manual cropping if it ""feels"" better. Needs some testing first..

The patch adds 4 new functions which - in future - will be used to return or echo the header_image's width and height:
get_header_image_width() - header_image_width()
get_header_image_height() - header_image_height()

If the whole uploading process would be filterable I would add this as a plugin, but I think it would be nice to have this feature in the core as well.

It is not ready for release yet though. E.g. need to add an explanation of the 3 states to be displayed to the user."	enhancement	new	normal	Future Release	Themes		normal		needs-patch 2nd-opinion
