BMP testing results from the Bitmap Test Suite #3574

Description

@Mimigris

In EasyRPG/TestGame#18, it was mentioned that the Bitmap Test Suite by David Costanzo that is in the Public Domain could be added to the TestGame. I'm currently working on adding it, with focus on assets that have a format accepted by RPG_RT.

Now, here are the instances where we are inaccurate (you can find more info about what each picture does on the Bitmap Test Suite website):

8bpp-1x6400 - EasyRPG does not render it:
Image

8bpp-topdown-320x240 - the TOP LEFT text is displayed in the bottom-left corner on RPG_RT:
Image

8bpp-pixels-not-in-palette - the colour choice is flat on RPG_RT:
Image

8bpp-no-palette - when setting it as a picture set to have transparency, the transparency is not set at the same location:
Image

8bpp-pixeldata-cropped - RPG_RT seems to be constant on how it is displayed, with the same part always in pink, meanwhile EasyRPG has a random behaviour, with the pixels potentially changing when setting the picture to be transparent, and can even crash when the picture is displayed:

Image

4bpp-pixeldata-cropped - 4 bits BMP is not supported by RPG_RT, so no comparison to do here, but the same issues than with 8bpp-pixeldata-cropped are also present here:
