Is there any functionality similar to the "color mode: blend/replace" dialog from the image editor in GMS1? It doesn't appear that there is any easy way to, say, replace a couple opaque pixels with semi-transparent ones, or replace semi-transparent pixels of one color with another. If you try to draw a semi-transparent pixel over an opaque pixel, you can only get a blend of the opaque color and the transparent color (drawing a semi-transparent yellow over an opaque red always results in an opaque orange), and if you draw a semi-transparent pixel over another transparent one, the color is blended and the highest alpha is kept resulting in a pixel that is the same opacity but a different color(ex. trying to replace a 128-alpha yellow with a 128-alpha red results in a 128-alpha orange). I've also tried using the color replace tool, but that only changes the color and not the alpha values(replacing a fully opaque black with a transparent red gives an opaque red). You can delete the pixels you want to replace and draw the new color over the blank space, but that's a pretty arduous solution and makes it really hard to experiment with different colors. I've scoured the interface and the manual - what am I missing?
