Fixes "./../art/file.png" causing duplicates when used in multiple systems, even if it refers to the same file.
Remove debug messages for SVGResource and ImageComponent.
1. Original width/height were being returned as integers, even though they can be floats (see SVGResource::getImageSize()). Function also renamed to be more descriptive (renamed to getSourceImageSize()).
2. Now we always round height and scale width from the rounded height when doing scaling, since SVG rasterization scale is determined from height. This seems to fix some 1px cutoff I was seeing, but I'm not sure if it still works for images with extreme aspect ratios that are taller rather than wider.
Should "just work" for any TextureResource::get("*.svg"). dynamic_cast it to an SVGResource and call rasterizeAt(w, h) if you need to re-rasterize it.
Only supports scaling that maintains aspect ratio.
You do not need res2h to build ES, only if you wish to modify resource
files.
Added a simple corner.png and bar.png for a border in the settings menu.
Added ImageComponent::setColorShift(unsigned int color) to change the
OpenGL color array.
Textures allocated with no path (e.g. the transition image which uses
copyScreen()) weren't being deinitialized with the renderer. Which meant
something else could take the old texture ID, and when the no-path texture
got destroyed, it would take a texture along with it.
Moved Opacity logic from ImageComponent to GuiComponent so any extender
of GuiComponent che implement its opacity logic.
Implemented Opacity logic for TextComponent (now text can have fade
animation)
The ResourceManager provides a unified interface for accessing resource
data, embedded or from the filesystem, with
initialization/deinitialization handled automatically behind the scenes.
It also keeps from creating duplicate resources (e.g. when two
ImageComponents use the same image file).
Audio still needs to be moved over to it.
