The goal of the changes made in this PR is to create something with this
effect ("Jonko" is in in green, the rest is in white):
"Dear god." Jonko quickly replied,
crestfallen.
In order to do this, I need to call `NE_RichTextRender3D` or
`NE_RichTextRender3DAlpha` three times: once to draw the first part of
the sentence with the white font, once to draw "Jonko" in turquoise, and
once to draw the remainder of the sentence in white again. In order to
ensure that text is being drawn in the correct location, I need the
position where the previous call stopped drawing, which leads to the
first change this PR makes: I have added a version of
`DSF_StringRenderDryRun` which accepts pointers to `final_x` and
`final_y` and stores the last position of `font->pointer_x` and
`font->pointer_y` in them and I have added a new variant of
`NE_RichTextRenderDryRun` called `NE_RichTextRenderDryRunWithPos` which
uses that DSF function and has analogous parameters.
These functions get us the position where we need to place the next
cursor, but the next issue is that currently NitroEngine and libDSF only
allow for specifying the position of the overall box to draw text in,
but not where to offset the cursor in that box. This leads to the
following problem ("Jonko" is in in green, the rest is in white):
"Dear god." Jonko quickly replied,
crestfallen.
Thus, the second change: I have introduced new versions of
`DSF_StringRender3D` and `DSF_StringRender3DAlpha` which accept an
`xStart` position that is added to the `pointerX`. Correspondingly, I
have added versions of `NE_RichTextRender3D` and
`NE_RichTextRender3DAlpha` that use these new functions as well.
Let me know if there are any issues with how I've written this (C is not
my forte, after all), but the first screenshot is this being tested in
production code.
This reverts commit 48ff37231f ("library: Remove unimplemented
functions from RichText system").
I thought the 3D drawing functions took a "depth" argument, but I was
wrong. I'm re-introducing the functions (and, this time, with an actual
implementation).
