I'm looking for a way to create sRGB raster images. Now, I could use Inkscape and just have it render to a raster format, but are there any image drawing tools other than Photoshop that work in sRGB?

Here's what I want to be able to do more specifically. Let's say the image is all one color. I want to be able to pick color 0x808080, which is in the sRGB colorspace. I want the file to write an image where every pixel is 0x808080. And then, when I read it, I can tell OpenGL that it's sRGB color data, so it will treat the 0x808080 color has being from the sRGB colorspace.

The important part is that, when I'm selecting colors in the tool, the colors I'm selecting are from the sRGB colorspace.
