Editing WoW:XML/BackdropTemplate (section)

=== config details ===

User defined 'backdropInfo' requirements:
* The backdropInfo table requires one, or both, of 'edgeFile' or 'bgFile', or will be ignored, and the backdrop will not be created.
<pre>
BACKDROP_DIALOG_32_32 = {
	bgFile = "Interface\\DialogFrame\\UI-DialogBox-Background",
	edgeFile = "Interface\\DialogFrame\\UI-DialogBox-Border",
	tile = true,
	tileEdge = true,
	tileSize = 32,
	edgeSize = 32,
	insets = { left = 11, right = 12, top = 12, bottom = 11 },
};
</pre>
* If using a user created backdropInfo table, it must be created before the Frame loads, so must be created in Lua in a lua file that loads first, before the file XML is loaded.

User defined color table requirements:
* A 'color table', or color constant, must be created with CreateColor(r, g, b, a) which creates a ColorMixin instance. BackdropTemplate will try to call GetRGB on the table and expects an 'r, g, b =' return.
<pre lang='lua'>
PURE_RED_COLOR				= CreateColor(0.8, 0, 0);
PAPER_FRAME_DARK_COLOR		= CreateColor(0.25, 0.1484375, 0.02)
</pre>
* The color constant must be created before the Frame loads, so must be created before the file XML is loaded in Lua, just like the 'backdropInfo' does.
